Interfaces are not yet supported but they are coming with VHDL2018, see section 6.5 of the draft VHDL2018 LRM: http://www.eda-twiki.org/twiki/pub/P1076/PrivateDocuments/P1076-2018.pdf Unfortunately as all VHDL designers will know we won't see EDA vendors adopting VHDL2018 any time soon.

I hadn't heard of this company before. They seem to be making a number of FPGA devices. Unfortunately all the docs are in Chinese. Anyone know much about them? http://www.anlogic.com/ Google can translate the web pages, but not the data sheets. Rick C.Article: 160753

Their Tang Dynasty tool looks interesting - as a Quartus user it looks very familiar (I note their download page has 'quartus' in the page title). Might be worth trying sometime. TheoArticle: 160754

Some companies are not easy to deal with. AGM seems to have English information but the one device I can use with FPGA+MCU has a Chinese datasheet with a different name. I also don't see any tools.

I'm not worried about them being better than the other FPGA companies. I'm= pretty interested in the parts being pretty inexpensive and available in e= asier to use packages.

Hi, I needed to provide convenient access to registers in an FPGA design intern= ally interconnected with Wishbone/IPbus bus. There is a wonderful tool - wb= gen2 in the OHWR directory, but it doesn't support nested slaves neither ve= ctors of registers. Therefore, I've decided to prepare a similar tool, base= d on wbgen2 concept, but written in Python. The first version is already available in https://github.com/wzab/addr_gen_= wb and is available under GPL v2 license. The solution is oriented on control applications not on high-traffic data t= ransfer. Therefore, it supports onle classic mode single accesses. Please note, that the code was written just in a few days, so it is not wel= l structured. However, I hope that it may be usefull for others. I'll appre= ciate any remarks, suggestions of improvements or bug fixes. With best regards, WojtekArticle: 160764

And if the quantity is lower than few 1000s then I probably don't care if it's 10 UDS or 17. 10CL016 comes with datasheet that I can read and with development tools that I can trust. If you propose me "40 kLUT for 5 USD" then there is a chance that I can start to get excited. BTW, as far as variable cost goes "40 kLUT for 5 USD" is pretty easy at 28nm or better. The problem here is how do you recover NRE. One have to sell more than 10M units. Probably much more.Article: 160765

We are not having the same conversation.=20 >=20 > Rick C.=20 >=20 > Tesla referral code -- https://ts.la/richard11209 I suspect, we are not belonging to the same branch of the Multiverse. In our branch we have thingies called "web search engines". The most popula= r of them is called "google". It's so popular that its name became a verb. So, in (on ?) our branch, when somebody does not know what is EP4CE10 he/sh= e googles for it. Then the person easily finds out that EP4CE10 is a low co= st FPGA from Altera Cyclone IV-E family released ~9 years. If the person is still interested he/she googles for 10CL010 and finds out = that it is another name for the same chip given to it by Altera (which in t= he mean time was acquired by Intel) when they decides to rename several SKU= s of Cyclone IV-E to Cyclone 10-LP and to reduce their prices. Comparing datasheets it's also pretty easy to come to conclusion that AG10K= F256 is the same chip as EP4CE10F256. That's how it works in (on?) our branch of the Multiverse. But yours is pro= bably different.=20Article: 160771
Hello folks,=20

I wanted to implement Modbus protocol on fpga. I don't know how to =
start? I read various documents on internet but didn't got any clear idea. =
basically my aim is to make package of this protocol. I am using Vhdl as la=
nguage. so i want process or say steps should i follow to make this protoco=
l working.If anybody has worked on this previously can share document it wi=
ll be great help.
thanks in advance..!!

One is Modbus RTU, using a UART with RS-485. On the hardware side you need a UART with a transmit enable control line. Everything else is in software. The other is Modbus TCP/IP over Ethernet. On the hardware side, you need Ethernet. Everything else is in software. So "Modbus on an FPGA" means having a processor (soft or hard) and software on the FPGA or the board, and a UART or Ethernet. Trying to implement Modbus directly in FPGA hardware without a processor is insanity.Article: 160773

I just wanted to know that are you suggesting to use external processor for implementation. and also i would like to know while writing vhdl program what steps should i follow.Article: 160774

It is entirely up to you if this is external to the FPGA, a hard core in the FPGA, or a soft core in the FPGA. > > and also i would like to know while writing vhdl program what steps > should i follow. > If you have to ask this, I would recommend that you drop the idea of an FPGA altogether. A $2 microcontroller will let you build a Modbus RTU slave on RS-485 - it will have a UART and all the processing power you need. If you are thinking of Modbus over Ethernet, your microcontroller will be around $5.
