Hi,
I am using mentor graphics tools eldo and xelga. Basically I need to use a wave processing function( namely "drv" :: derivative ). However it would save a lot of time if I could do this in eldo itself. is it possible to include this in the eldo input file. if so, how??

Any other method of finding derivative is also ok. Further I am not plotting the output of a transient simulation but extracting the oscillation frequency at different parameter values. Then i need the derivative to compute the VCO constant.

Regards,
Kartik
