Failed To Open Vhdl File In Rb Mode

To correct the problem, edit your system or local modelsim.ini file to replace "ieee = $MODEL_TECH/../ieee" with "ieee = $MODEL_TECH/../vital2000". This is done in order to achieve usable performance in board-level verification and, to avoid issues over intellectual property. Check This Out

You may need to recompile the FMF libraries. FMF can contact the vendor but you, the customer carry more weight with them.

The data cannot be read directly into a signal.That is why I have first read it into avariableand then assigned it into a signal. Instead, timing information resides in a separate file with the same name but an extention of ".ftm" or, ".ftmv" for Verilog models. Why do I get the following error when compiling models with ModelSim? thanx for guide.

The example is meant for just a basic introduction for file handling in VHDL.There are pretty largenumberof options when itcomesto file handling,but I will post them in future. --include this library Advertisements Latest Threads Complete Newb Joe Strong posted Dec 13, 2016 VHDL Subtraction two’s complement Alenx posted Dec 13, 2016 For Loop netOwen posted Nov 29, 2016 vhdl code chandan khan In the example I have shown,I have two files.First one is named as "1.txt" and is my input file.The values will be read from this fileandsimply copied to the second file it is a tiny problem...i hope u can solve it soon feed us back with what u did Salma :D 17th May 2006,08:56 17th May 2006,12:16 #5 Blowfishie Junior

Test bench looks like below. ------------------------- .... Its just that I am waiting for some time for updating the signals. Don't forget, you can also ask questions on the FMF blog, or go to the Forum to discuss issues with other engineers. No, create an account now.

Do you know if the .mif file is ever used by ngdbuild? When and how to use "constant"? We are unable to accept your feedback at this time.

Do I HAVE to backannotate to use these models?

Thease timing files contain chunks of SDF (Standard Delay Format) code embedded in XML. The preferred action is to contact the manufacturer and ask them to commission FMF to create the model you need. It seems that you don't have created the file you are trying to read, or it isn't located in the path you are indicating. 17th May 2006,07:10 #3 wolfheart_2001 Member level navigate here Constant "unitdelay01z" is type vitaldelaytype01z; expecting type vitaldelaytype01z The ModelSim installation defaults to VITAL95.
