How to create an dll in VHDL?
How could I create a ".dll" file with VHDL to use it in another
programe (like in a bigger Delphi or C programe)? Is it possible? Thanksss!!!!

This page talks about starting a simulation from a C program: http://ghdl.free.fr/ghdl/Starting-a-...n-program.html BTW: GHDL is working very nicely these days and it even runs on my Mac. I've been using the latest version (0.16) for the past few weeks and I haven't run into any problems with it. It's good to have an open-source VHDL compiler/simulator that actually works. Phil |

"GHDL implements nearly all of the VHDL87 (common name for IEEE 1076-1987) standard, most features of VHDL93 (aka IEEE 1076-1993) and the protected types of VHDL00 (aka IEEE 1076a or IEEE 1076-2000)." Sounds like it still has a long way to go. Is there a clear statement anywhere of exactly which language features it supports? The online GHDL guide didn't want to tell me anything concrete.

Maybe I'm not doing anything really fancy, but so far it's been working fine for me. I'm developing a DSP-like design with some fixed-point math and several lookuptables for things like exp(). The only think I can say is give it a try and see if it works for you. If not, file a bug report. I've got it running on Windows/Cygwin (which took me a day or two to get it to compile) and MacOSX.

However, could you please check your version with this file? It is a practical design that I use for breaking synthesisers. A simulator should have no problem with it. http://fractional-divider.tripod.com/fracn20.zip (If tripod won't let you have it, visit this site first: http://fractional-divider.tripod.com/ ) There's a testbench in the "version 9" download, also available on that site.

That's good news, particularly considering that Modelsim versions prior to 5.7b couldn't run the code correctly, and Synopsys tools still can't compile it. Regards, Allan |
