Title: oppoint gm, gds etc in transient ocean analysis Post by makelo on Apr 7th, 2010, 11:00am I am trying to do a circuit simulation to report operating point conditions (gm, gds, vth, etc) after the circuit has started up and run for a few 100ns. I need to report the results in Ocean for further analysis. I can get at some of the information with infotimes in transient analysis followed by numerous mouse clicks in the results browser, but this process is not easily repeatable. I need the results in Ocean so that they are repeatable. I looked through a few other threads but I didn't see how to get gm, gds etc.: http://www.designers-guide.org/Forum/YaBB.pl?num=1225386917 Here is my analysis code that I am currently using: Code:
The 'analsysOrder command works, but the dc anal is unrelated to the transient anal. |
Title: Re: oppoint gm, gds etc in transient ocean analysis Post by makelo on Apr 7th, 2010, 12:38pm After further experimenting with my Ocean code I found that adding the ?restart "no" command to the dc analysis statement combined with the 'analysisiOrder command gets the dc analysis to occur after the transient analysis. But I am still unsure about getting out the OpPoint values. Code:
Using the v() command gives a value that looks plausible, but I think this means, 'find the voltage of N1:gm' which is confusing. Is there a better way to do this? An alternate way at the data is: Code:
Is this better? |
