Title: How to control the number of points in the print file?Thanks. Post by holddreams on Sep 16th, 2009, 6:30am In the following netlist, it writes .print tran *+ v_sweep = par('resolution*(time-sweep_d)/step_t + swstart') + v_sweep = v(v_sweep) + i_pulldown = par('0') + i_gndclamp = i(vgnd_clamp) + i_pullup = par('0') + i_powerclamp = i(vpower_clamp) after running the simulation, there will be a *.print file, I want to know how to control the number of points measured, anyone can give some suggestions?

Title: Re: How to control the number of points in the print file?Thanks. Post by ywguo on Sep 16th, 2009, 10:23pm Hi holddreams, What's your simulation environment? If simulate in ADE, it is easy to print the transient outputs and parameters with specified steps. Open Calculator, choose the node voltage or parameters, click Tools -> Table.... Then a window named Calculator Results Display pops up. Choose Range, fill in start/End and Step/Scale as what you want. Best Regards, Yawei |

Title: Re: How to control the number of points in the print file?Thanks. Post by holddreams on Sep 19th, 2009, 11:50pm I use spectre stand alone to simulate the circuit. That is ,given a test.scs, then run "spectre test.scs" can get the simulation results. I tried to change the step/stop time, but failed. Also, I use strobeperiod option in the test.scs, however,the print file also contain some information which is not just by strobeperiod of time. Any other suggestions? Thanks. ywguo wrote on Sep 16th, 2009, 10:23pm:
