Since I am currently pursuing a logic design, Would ModelSim be a good option for working with and, or, not gates and being able to watch timing issues, etc? ModelSim is an HDL simulator. As such, you will need HDL models of whatever you want to simulate. And it's digital only -- no analog. It will do timing simulations, assuming you include the worst-case timing information in your models, or you back-annotate with an SDF file. But it won't do timing ANALYSIS, which is a different problem. So, if your logic design is going to live in an FPGA or CPLD (and it probably will, it ends up being less expensive and more reliable than old-skool 74xxx-series TTL), HDL simulation is a requirement. Of course you will need to learn an HDL. 2 Monitors?????????? Dang! Don't these authors ever use their own stuff? Two monitors are ABSOLUTELY necessary. HDL in one display (a couple of emacs windows, etc) and the ModelSim wave window in the other. -a |
