ngspice BSIM examples that work using DuSpice /ngspice are not working using Qucs-S. Two issues came up: 1. BSIM4_prj - BSIM4 files work using ngspice but under Qucs-S produce "Alberto...
Qucs-S and Qucs is using the symbol for depletion mode MOSFET when placing an enhancement mode MOSFET onto the schematic. The symbol is correct in the left component or library...
Previously I asked about having the correct Spice symbols for N/P enhancement and depletion power MOSFETs with 3 pins, (D-G-S) to match up with Spice models provided by manufacturers. The...
If I want to cut or copy more than one item, I must use the Edit menu. If I select a group of items, as soon as I try to...
Is a potentiometer in a future release? Since log or alternate taper pots are pretty much gone today a simple linear one would suffice. The ability to alter resistance via...
Is there a reason Qucs-S won't do a simple DC operating point (.op)? Qucs does it and I assume ngspice will do it as well. If I add say a...
As an exercise I ran some simulations using 4 different 555 timer models. I used the DuSpice GUI to confirm all worked with ngspice. Only 1 model (UA555.lib) worked when...
During some vacuum tube amplifier modeling, the tube model 6V6.sch based on 6V6.lib is causing Qucs-S 1.0.0 and 0.0.24 to abruptly close without generating any files when I try to...
I'm getting weird results trying to "port" a Qucs Varactor simulation over to Qucs-S. I want to use "Varactor_Model.sch" in circuits. I used the built in varactor model for debugging....
Gmail and Yahoo blocked me from sending you this attachment for the email I sent earlier. Email text: I did more work on the BSIM example projects. Strangely I cannot...
