Hi everybody,

I have tried the examples in paper "Simulating Switched-Capacitor Filters with SpectreRF".

In the sc-filter netlist, the vin shows as following:

Vin  (in gnd) vsource type=dc pacmag=1.0
+ ampl=INPUT_AMPL freq=INPUT_FREQ fundname="input"

But I have tried all the ways in my "vsource" setup for my own circuit, I either could get the following specification for two differential vsources:

V4 (Vin net082) vsource type=dc pacmag=500.0m pacphase=180
V1 (Vip net082) vsource type=dc pacmag=500.0m

or I could get:

V4 (Vin net082) vsource type=sine freq=10K ampl=500m sinephase=180 \
       sinedc=2.5 pacmag=500.0m pacphase=180 fundname="input2"
V1 (Vip net082) vsource type=sine freq=10K ampl=500m sinedc=2.5 \

Then all of above netlists will work for PSS and PAC. Here is my question. I have run spectre in command line and open waveform with AWD(analog waveform display),
then in the sc-filter example, it displays:

                                                                                        |
                                                                                             |TFin-pac
scf.raw-Run1-|clockAlone-td.pss
                                                                                             |clockAlone-tran.pss
                           ........
   
Then I found that through  "clockAlone-tran.pss", I can get figure 10 bottom plot in paper page 19. But with my own circuit setup, after running spectre, I only can get

pss-fd.pss
pss-td.pss

I couldn't get "pss-tran.pss" for my own circuit.

Did anybody, by any chance, try and somhow get pss-tran.pss in his or her own circuit?
