I did something like that. I mean its by far not a library, but maybe a starting point for you. My "real life" system was something like that: ADC <--> FPGA <--> DSP
For my testbench I the wrote an entity which implements the ADC interface, but reads its data from a file. To write output data something similar could be done on the other side. I just included it in my "normal" synthesizable entities and surrounded it with pragmas that take it out for the actual (non-simulation) pragmas. Here is the interesting part of my code: https://gist.github.com/StefanD986/4ce18416d3e1617a2b3bcc62d164618e I can say it worked quite good for me and the performance was much better than using the wave output of ghdl. Since on Linux/Unix inter process communication can be achieved relatively easily with "special files" like pipes etc, it shouldn't be to hard to feed-in input or forward outputs over UDP/TCP, serial ports etc, e.g. with mkfifo and netcat or so. 2016-06-03 10:52 GMT+02:00 Vít Fábera <fab...@fd.cvut.cz>: > Hello, > > we would like to use GHDL as simulator as real simulator. > it means simulate FSMs with real input and set real outputs. > > We would like to create library with commands like writeline, > which would send data for example to serial port, to network > via UDP/TCP packet and, naturaly, with function like read. > > Does anybody create such library or similar extension of GHDL? > > > Thean you for answer > > > Vit Fabera > Faculty of Transportation Sciences > Czech Technical University > > _______________________________________________ > Ghdl-discuss mailing list > Ghdl-discuss@gna.org > https://mail.gna.org/listinfo/ghdl-discuss >
