I found two bugs in the cadence IC5141 ADE.
(1) When a schematic contains a instance of vsin , the exported netlist for vsin is as following:

V1 (1 0) vsource dc=1 mag=1 phase=0 sinedc=1 ampl=1 freq=1K

and the bug is that there is not the type declatation "type=sine" in the netlist for sine voltage source, the same as isin vpulse ipulse etc.
I've check the the netlist for vin and vpulse in the IC4.4.6, and The netlist for sine contains the "type=sine". that's the difference in the two versions for the same schematics.

(2) When "pPar()" parameter appears in the netlist, Spectre would found error with following massages:

Function 'pPar' is undefined or is used recursively.

Is anyone encounter the same problems with me?
And can anyone help me?

Thank you!

hi,

You said it does not specifies the type...... then wat does it mean by sinedc.

plz check it out and let me know.

Added after 3 minutes:

hi again,

you checked the sch using IC5141 & IC446.

Is the results same or different.?

do check it out.

In the IC446, the exported netlist is:

V1 (1 0) vsource dc=1 mag=1 phase=0 type =sine sinedc=1 ampl=1 freq=1K

but in the IC5141, the netlist is :

V1 (1 0) vsource dc=1 mag=1 phase=0 sinedc=1 ampl=1 freq=1K

set the CDS_Netlisting_Mode to Analog in your envirnomental variables will solve problem 1.

Yes, CDS_Netlisting_Mode must be correct.
