spectre error

hi sir,

iam simulating on common source amplifier by using spectre simulator.I given source signal as a vpulse it taken in my analog lib.

i given all the Vpulse waveforms parameters (i.e Ac magnitude,ac phase,Dc voltage ,voltage1,voltage2, time period,rise time,fall time ,delay time & pulse width) then simulation run throug netelist &run button of spectre tool (ADE L)

BUT IT SHOWS ERROR

i.e

Error found by spectre during hierarchy flattening.

ERROR (CMI-2194): V1: Waveform type must be specified if any waveform parameters are given.

Time for EDB Visiting: CPU = 999 us, elapsed = 885.963 us.

Time accumulated: CPU = 1.71174 s, elapsed = 2.29704 s.

Peak resident memory used = 58.2 Mbytes.

spectre terminated prematurely due to fatal error.

my aim is to find out DC gain,Unity-gain frequency & slew rate

Thanks,

Hi venkata siva

Would you please post the line in the spectre netlist for "V1"? E.g.

V1 (net05 OUT) vsource dc=0 type=dc
V2 (IN 0) vsource dc=VDD/2 type=sine freq=1M ampl=50.0m mag=1

Thanks

hi Quek
These are the v0 & v1 values given by me
V0 (vdd! 0) vsource dc=3.3 type=dc
V1 (Vin 0) vsource dc=Vindc mag=1 phase=0 type=sine delay=1p ampl=2.5
thanks,

My guess is that you don't have $CDS_Netlisting_Mode set. You should do:
setenv CDS_Netlisting_Mode Analog
if using csh, or if using bash/ksh it would be:
export CDS_Netlisting_Mode=Analog
before starting virtuoso/icfb. You may need to do a Simulation->Netlist->Recreate in ADE.
Andrew.
