Description
Hi Tim,
this is just what I was looking for. For a while now I have been looking at logic simulators to quickly wire up some circuits and tune them before building them. There are some graphical tools around for cheap or even free. But I was never impressed enough to use any of them. Writing a good simulator is hard. So I was thinking of simulating circuits in Verilog, but writing proper representations of 7400 series logic chips takes a bit more experience than I can presently muster. The other problem with all these tools was that they have a very spotty coverage of actual chips. So, in the end it was not possible to build useful circuits or more to the point, the circuits I actually needed.
Your library suffers the same problem of course. But you are just starting out and you have already an impressive list. What is more, you seem committed to make the library as complete as it reasonably can be. That is very inspiring.
If you are looking for a list of chips that might be more immediately useful, here is a list of chips I presently need for a project I am working on:
- 74xx4040
- 74xx40103
- 74xx74
- 74xx85 (I think you got that already)
There are some other things that might be useful at some point, but I am not sure they are doable in Verilog, since they are (partially) analog:
- 74xx4046 (PLL)
- 74xx123 (Mono Flop)
In addition, some auxiliary circuits might me nice for a broader audience, such as an oscillator and dynamic triggers (often implemented as RC circuits in the real world).
If you need support, at present I don't feel firm enough to contribute code, but I can chip in with documentation if that is of interest.
Regards
