#196 Simulation becomes very slow if SPAR and TRAN active on same schematic

[Werner Simbuerger]

Simulation becomes very slow if S-parameter and transient simulation block active on same schematic:

Example: <<ORT-1200_prj.zip>>

1. please simulate "top_spar.sch" -> fast S-parameter simulation
2. please simulate "top_tran.sch" -> fast transient simulation
3. please simulate "top.sch" -> slow simulation of transient and S-parameter (why?)

There should be no reason why the combined S-parameter and transient simulation of the same circuit becomes very slow.

Best regards,
Werner

"top_1.sch" is the better combined schematic to simulate both S-parameter and transient of same circuit

Update: I found the error, unfortunately it was my fault - sorry - I forgot to set the port power to zero, which did cause transient exitation at 1 GHz

Please close or delete this case... Thx, Werner

no problem, good to know that now it works fine :)
