Re: [Ghdl-discuss] Status of the VPI / VHPI interfaces implementation
Thanks Martin and yg! These are very, very interesting examples. It seems GHDL's VHPI is really powerful, so congratulations Tristan! yg, your code seems to work with ghdl 0.34dev (I haven't tried the parallel port example, and have to further tinker with the framebuffer example: I think I am having permission problems accessing /dev/fb0). Thanks for the clean code with comments :) Kind regards, Hipólito On Mon, Apr 24, 2017 at 1:17 PM, wrote: > Le 2017-04-24 12:32, Martin Strubel a écrit : > >> Hi, >> >> >>> What is the status of the VPI / VHPI / interfacing to other languages >>> implementation on GHDL? >>> >>> >> For me, the VHPI i/f turned out to be very robust and way more >> powerful than what Modelsim has to offer.

Hi, What is the status of the VPI / VHPI / interfacing to other languages implementation on GHDL? For me, the VHPI i/f turned out to be very robust and way more powerful than what Modelsim has to offer. You will have to dig through some code though, and you might want to search this list's archive for posts about whygee's example code or the keyword "ghdlex", the latter being some kind of loosely knitted together linux library functions for virtual interfaces (FIFO/pipe/UART) or busses allowing co-simulation with Python, qemu, et al.

What is the status of the VPI / VHPI / interfacing to other languages implementation on GHDL? I have been able to compile and run the external sin() example here: http://ghdl.readthedocs.io/en/latest/GHDL_implementation_of_VHDL.html#interfacing-to-other-languages , but I'm having trouble getting a simple custom .c/.o file linked with GHDL. ¿Do I need to create a library with my custom functions, or is there a way to link against a specific object code file during the elaboration phase?
