Hello
It occurs error during synthesis.
The error is:
sequential mapping has detected that cell 'LOAD15_reload' has uses both the
asynchronous 'set' and 'clear' pins.
The fragment of the code is below:
always @(posedge GATE or posedge intoCounter)
if (GATE) begin
if (MODE15) begin
if ((TRIGGER_WORKS) || (TRIGGER_WORKS & COUNT_ENABLE))
LOAD15_reload=1'b1;
else
LOAD15_reload=1'b0;
end
end
else begin
if (MODE15)
LOAD15_reload=1'b0;
end
I request for reply.
With regards
Tomek

Be *very* careful with clauses like this.
Since you've stated (or at least they expect you to state) that you
won't disclose [commercially] confidential information to them, you
might find yourself in a *very* difficult situation if you're asked to
"invent" during the interview.
If the company asked you to describe how, for example, you'd design a
data logger, what comeback would you have if they later used your
ideas in one of their designs?

Article: 24654The error is just what it says. You are trying to async set to either a 1 or a 0 depending on ((TRIGGER_WORKS) || (TRIGGER_WORKS & COUNT_ENABLE)). This means that you need both an async reset and an async set. The FFs can not support both, you have to chose one or the other.

I work ludicrous hours, I drink caffeine and have the worlds most disturbed diet. I consider psychology and psychiatry one rung at least below witch doctors. I don't do psych tests, pee in bottles or sign anything to get an interview and neither should anyone else have to. At the end of the day there is a world wide shortage of good engineers so if they get too obnoxious with their tests they won't find many takers, and will end up the losers.Article: 24658
I think it would wind up being bigger and more complex than the scaling accumulator or serial booth. If you need serial output or extreme bit rates (no carry chain) the serial booth might make sense, otherwise the fast carry chain makes the scaling accumulator smaller. The serial booth is serial by parallel with a serial output. Scaling accumulator is serial by parallel with parallel output. A shift register and latch will make the other input serial. jj_okocha@my-deja.com wrote: > > > Baugh-Wooley is a parallel algorithm by definition.

there are some older appnotes for the 4K family that describe async fifos for the CLB RAM. In any case, the techniques are the same as for the block RAM except that you use the CLB RAM in in dual port mode. I thought the xilinx fifo core gave you a choice of which kind of ram it uses.

Well put and agreed. It is a two-way street.Article: 24662
NDA are definitely enforceable, but there must be a compromise to the promise that causes damages, which are loosly defined. The point of the thread initially was merely the point that in order to get a fell for each other, we have to know what each other is doing, and capable of. "We'd like to give you enough info so that we can figure out if you can do the job, and also find out if you are interested. please don't compromise this." The sticky part is that of competitive industries. Typically, even non-compete agreements have tended to be somewhat uneforceable, and often not worth pursuing. It depends on the level of the employee and the amount of direct comprison. I know a very large company who has said they will not hire me into a certain situation because they have ethics concerns about acquiring the braingpower behind both a competitor's technolgy, and a partner (I have been involved in both). Thus, the problem is that they want me to work, and will hire me, just not in their desired roll. Given some time separation, they will then work me into that product/research group. And emphasizing your point, the "perspective" of importance by the hiring company tends to be the defining roll, not the actual value or importance. What are ya gonna do? Catch 22. Sign it and see, or go elsewhere. I personally haven't found it so difficult to sign the NDA. It's dependent upon the level of employment, and the directness of competition. I was once hired by a relative competitor, but not directly competitive on the work I was doing. I was very friendly with my previous employer. They were ready to send warning letters, reminding me of my NDAs. Then, rethought it and felt that our good relationship (I left not to go to work for another company, but to move to another area, which then required me to find work) warranted trust. I have not, to this day, renigged on that. But, I can understand their desire to protect themselves competitively. Company's should, This case was isolated - i had a lot of personal ties.Article: 24663

OK, here is the scoop. Probably means they are a patent orientated company vs proprietary. I am fairly familiar with the patent process. Basically, it is a public disclosure of technology, methods, or design in exchange for exclusive rights for a 17 year period. In addition to the obvious, there are several reasons for a patent not being granted. One of these is the information is already publically known. For example, someone is using xyz to develop product widget, you get a paper published that says company xyz is doing xyz to make a widget or even leak the info to other companies such that it is widely known before the patent is granted, the patent department will refuse to grant the patent. The company is screwed to put it mildly. Lot's of things are quite easily reverse engineered. For some, like medical devices or safety devices<seat belts, fire exstinguishers, etc> you have to disclose every detail about the device including manufacturering methods, componets, testing procedures. It isn't like reverse engineering, more like following a cookbook. The 5 year thing probably just means they will have all the legal protection they need by that time or will have progressed to the point where any information they gave out is obsolete. Under the circumstances, I would probably tell people *NOT* to buy stock in any company in that position that didn't ask people to sign an NDA, just common sense. But not a big thing if you don't feel comfortable working for a company that does it. Just don't work there and don't hold a grudge. Understand that they are doing it because they have to, nothing personal. If I were you, I would go to one of the patent databases on the web and dig up all the patents the company has so far just for personal info. You may be able to deduce where they are headed and how much you want to be involved. Could be anything from biowarefare to something near and dear to your heart that are willing to sign the NDA for.Article: 24664

Maybe the issue is that the "posedge intoCounter" does not seem to be used in the block, or maybe the final "LOAD15_reload=1'b0;" which is in the else clause of "if (GATE)" is confusing it, since this I think mean that since I only enter this block if either GATE or intoCounter have a posedge, and the else clause means that it wasn't posedge GATE, so it must be posedge intoCounter, this implies a FF with two clock pins??? >Tomasz Brychcy wrote: >> >> Hello >> It occurs error during synthesis. >> The error is: >> sequential mapping has detected that cell 'LOAD15_reload' has uses both the >> asynchronous 'set' and 'clear' pins. >> >> The fragment of the code is below: >> >> always @(posedge GATE or posedge intoCounter) >> >> if (GATE) begin >> if (MODE15) begin >> if ((TRIGGER_WORKS) || (TRIGGER_WORKS & COUNT_ENABLE)) >> LOAD15_reload=1'b1; >> else >> LOAD15_reload=1'b0; >> end >> end >> else begin >> if (MODE15) >> LOAD15_reload=1'b0; >> end >> >> I request for reply. >> >> With regards >> >> Tomek >> >> T.Brychcy@ime.pz.zgora.pl Philip Freidin Mindspring that acquired Earthlink that acquired Netcom has decided to kill off all Shell accounts, including mine.

There is a superb 10 page report on "Extreme Lithography" by Keith
Diefendorff in the June 2000 Microprocessor Report.
Diefendorff says that three years ago, candidates for next-generation
lithography were
* X-ray lithography
* ion-projection lithography
* e-beam direct write
* electron-projection lithography (EPL)
* extreme-UV lithography (EUVL)
but now through "superhuman" progress, EUVL has become a leading candidate
alongside EPL. The article goes into loving detail about the VNL+EUV LLC's
EUVL engineering test stand (ETS), "a complete 13.4 nm stepper capable of
imaging 70 nm features on a 200 mm wafer ..."
According to the article, the ETS illuminator stage is powered by a 1700 W
pulsed YAG laser which excites a jet of neon gas into a hot plasma which
emits 10 W of EUW at 13.4 nm. A set of mirrors converges some of this into
a 1 W stripe that illuminates the 4 X reflective mask. The reflected EUV is
4:1 reduced through a 4 mirror camera and illuminates the wafer. It's a
step-and-scan system (the mask is scanned as the wafer is scanned). The
mirrors ("reflecting the unreflectable") are made to astonishing precision.
The article celebrates how so many apparently "insurmountable" obstacles
have been overcome. Amazing stuff, but more problems remain to be solved
en route to production tools (scheduled "late 2005").

I don't get it: Why would any interviewer discuss patent-worthy details with an applicant? You try to hire somebody who is smart and energetic and will be loyal. And as an interviewer you also have to be smart and cunning, so as not to divulge big secerts. By the way, in the US you have a full year to apply for your patent AFTER you have told anybody or everybody everything about it, including a published magazine article printed in 100,000 copies.

In the case of seat belts (the usual 3-point harness, I think), Volvo patented it but have made use of the patent royalty free for altruistic reasons. Ciao, Peter K. -- Peter J.

Sorry, I think my explanation wasn't very clear. The idea is to have
a specialized hardware for each course. For example:
COURSE 1: Data Communications
--------
Hardware necessary: USART and manchester encoder/decoder
COURSE 2: Microprocessors
--------
Hardware necessary: 8051 microcontroller
COURSE 3: Computer architecture
--------
Hardware necessary: RISC CPU
COURSE 4: ...
--------
I'll use the same board, with the same chips (a big FPGA), in different
courses. Students from COURSE 1, for instance, do not need to use an
8051, and so they will download to the board the bitstream for COURSE 1,
which has only the USART and the manchester encoder/decoder. There are
some extra details related to the prototyping area available on the
board, but I think they are not relevant in this discussion.

I'd not sign and I haven't ever done so, for a job interview, in the nearly 30 years I've been in business. There hasn't been a need yet. I suppose if the business was interested in sitting down with me to explain in great detail, on paper as an addendum, what exactly it was they intended and if it made sense when made concrete that way, I might. But for a job interview, that sounds like a big burden to start on. We'd probably both be better off saving the effort. No NDAs just for a job interview. The fact that some people are in a bad enough situation, job wise, to need to sign such things doesn't make them sensible. They aren't. However, I'll have to defer on whether there is substance with which to enforce them on. I don't really know. But it doesn't seem that there is much worthy of enforcement, since there is no way the signer knows what they are expected to do under it. They probably don't know, even after they leave. There is no meeting of the minds and probably no value received. But I'm not an attorney. It's still stupid to sign one for an interview, in my opinion. JonArticle: 24672

(less than half...120Kbps vs 300Kbps). How are you accessing the port? With a dedicated kernel driver? If you're doing it with one of the generic port drivers, there's a tremendous amount of overhead per I/O. I use a JTAG driver which transfers an entire serial bitstream with a single user-mode I/O call, which means the speed is almost entirely limited by the parallel port hardware. For a standard port, the theoretical limit is about 500kbps, and even quite a simple driver can get close to that. -- Steve Rencontre http://www.rsn-tech.co.uk //#include <disclaimer.h>Article: 24673
I thought of this, but I decided that this was not the best way to handle the matter. I am not looking to create any problems, which this would do. I decided it was best to deal with the issue in a direct and straight forward manner. Then they can't say, "no one has ever complained about this before". I am writing a longer post to describe my experience in the interview this morning. I should have it done later tonight.

Ok, so assume that instead of having worked for those two companies, you instead had interviewed with both of them where they had you sign NDAs and told you "valuable" secret information. Wouldn't you be in the same position of needing to work in a different area with your new employer? Certainly there is not the same degree of concern. But it is the same concern and you would be exposing yourself to a potential lawsuit. > And emphasizing your point, the "perspective" of importance by the hiring > company > tends to be the defining roll, not the actual value or importance. > > What are ya gonna do? Catch 22. Sign it and see, or go elsewhere. > I personally haven't found it so difficult to sign the NDA. > It's dependent upon the level of employment, and the directness of > competition. I don't understand the "level of employment" issue. In an interview there is *NO* level of employment. Or are you saying the level of the job? Certainly a VP would be exposed to sensitive information. But how would you ever protect yourself (the hiring company) from the "valuable" information getting back to the present employer? An NDA will only protect a company if you can show that information was leaked from your company. -- Rick Collins rick.collins@XYarius.com Ignore the reply address.
