Composing input.scs with cmdline (spectre) (Read 6347 times)

chase.ng Community Member Offline Posts: 77 penang/malaysia	Composing input.scs with cmdline (spectre) Feb 14^th, 2006, 5:43am Hi all, Anyone know how to compose spectre input.scs using command line? Other than clicking the green traffic light in the analog design environment GUI. I need to automate some for the simulations. Thanks. CHASE

The only limitation is that you can't create a netlist from the ocean executable - but you can from DFII executables (e.g. icms. If you don't want it to be graphical, you can always use icms -nograph -restore myScript.ocn . Regards, Andrew.

I thought it cannot be used. Chase

Nothing you can do about that, sorry! Andrew.
