Title: defining user waveforms and functions in Cadence Post by sutapanaki66 on Jan 29th, 2008, 9:03pm Hi, I recently had to make a transition from Mentor's Eldo to Analog artist for analog simulations. I used to work a lot in eldo with user- defined waveforms. The command there is .defwave <name> <expression> - basically you get the idea, one can define new waveforms from existing waveforms by putting them in some sort of an expression. This can be nested further to define waveforms based on already defined waveforms or mixing user-defined waveforms with waveforms coming directly from simulation like V and I. I was wondering is there such a possibility in analog artist? It being a widely used simulator I just can not imagine that there is nothing there for such a useful thing, so may be I just don't know it. So, I'll appreciate a lot any suggestions and they'll be also of great help. |
Title: Re: defining user waveforms and functions in Caden Post by Frank Wiedmann on Jan 29th, 2008, 11:31pm You can define equations in the "Outputs -> Setup..." form, most easily by getting the expressions from the calculator. I don't think that it's possible to nest expressions, though. |
Title: Re: defining user waveforms and functions in Caden Post by sutapanaki66 on Jan 30th, 2008, 11:59am Is it possible to write expressions in a file which then I can include in the simulation? I assume there should be also some specific syntax when writing? |
