Hi, Is there a guide somewhere that can show me how to transform AMS simulation results to IBIS? What do I need to export from the AMS simulation in order to create and IBIS file with the model integrity tool? (the Help button doesn’t help much) Thanks, Moshe
Moshekarako, Here is a reply from Cadence engineering: "If the AMS simulator that you are using is PSpice, then download the how-to kit "Creating IBIS Models using PSpice and Allegro PCB SI Model Integrity" at the following URL: http://www.cadence.com/community/allegro/pcb_si/tr.aspx?type=Modeling If, however, you are using ADE/Spectre for your circuit simulations, then a how-to kit for this will be posted next week. If you just want to know how to format the data for Model Integrity, use the following format in a file with a .lis extension: ****** transient analysis tnom= 25 temp= 50 vpower= 5.000000e+00 pulldown_ref= 0.000000e+00 gnd_cl_ref= 0.000000e+00 pullup_ref= 5.000000e+00 power_cl_ref= 5.000000e+00 time v_sweep i_pulldown i_gndclamp i_pullup i_powerclamp ***** job concluded ****** transient analysis tnom= 25 temp= 50 vpower= 5.000000e+00 vfixture_pd_on= 5.000000e+00 vfixture_pd_off= 5.000000e+00 vfixture_pu_on= 0.000000e+00 vfixture_pu_off= 0.000000e+00 rfixture_pd_on= 5.000000e+01 rfixture_pd_off= 5.000000e+01 rfixture_pu_on= 5.000000e+01 rfixture_pu_off= 5.000000e+01 cfixture_pd_on= 0.000000e+00 cfixture_pd_off= 0.000000e+00 cfixture_pu_on= 0.000000e+00 cfixture_pu_off= 0.000000e+00 time pulldown_on pulldown_off pullup_on pullup_off ***** job concluded Moderator
