Re: Edge triggered b-source logic and integrated averaging in LTspice
Hello Vlad (and other group members), Earlier today I received a message from Mike. There is a now a new update of LTspice available in which this minor bug has been squashed. ---In

How To Add Potentiometer
"snopro.olmstead23" (Surpher) asked how to add a potentiometer in LTspice. Your message hasn't shown up here yet. I guess Yahoo's servers are still working on it. Please no need to send the same

Re: Saving and restoring inductor current
Hello analogspiceman That's a nice trick, thank you. The penalty shouldn't be that much if not too many inductors are used, for example a SMPS could really use that. Even filt

Re: 74hc_v.lib file
Eric asked about the file "74hc_v.lib", needed in a downloaded simulation. I don't know if you found the answer to your question already (the replies I received might not be in order). However, the

Re: Saving and restoring inductor current
Hello analogspiceman. Thank you for enlightening me. I added the following to my collection of models: .subckt Lrememb 1 2 .param L=1 Rser=1m Rpar=1/Gmin ic=0 C1 3 0 {L} Rser={1/Rpar} Rpar={1/Rser}

Hi Eric. I opened your circuit and everything was modeled. I just did: .tran 0 10m 0 uic I have installed libraries in ../Documenty/LTspiceXVII/ .. You can find it on my page:

Re: 74hc_v.lib file
Hi Helmut, I'm sorry I found the 74hc595 in the files which will also do and has both the .asy and .lib files. Pls no need to send the .lib of the 74194. Thanks and best regards, Eric

74hc_v.lib file
Hi Helmut, Do you happen to have still the "74hc_v.lib file" used in the "74194 test.asc" schematic? It is not inside the zip file so I could not load it into the "sub" directory. The schematic would

Saving and restoring inductor current
LTspice can save and restore node voltages, but not branch currents. This means that by using ".savebias time=<tstop>" and ".loadbias" a simulation with inductors is only partially saved and restored

Re: Using BV exp(), log() for numerical compression ,wrong result ?
Hi, Andy: Before your explanation, I didn't notice "complex logarithm" is a special case, maybe not supposed to be supported by any SPICE. About the compression application, I didn't really have the
