Re: New Feature Released & Opamp Modeling
Jon, You probably want to make the Model and Instance name visible in the .asy file and nothing else. THE VALUE SHOULD BE LEFT BLANK in both the .asy and instance, unless you want to add parameters to

Re: New Feature Released & Opamp Modeling
I guess I'm asking this because the .ASY I currently use automatically displays the Value attribute. But the new drop-down for the SpiceModel only changes the SpiceModel attribute (perhaps, as it

TRIAC model
Hello, I'm new to this group and I don't have experience working with Spice models. Someone can please help me or point me to the right direction so I can make a TRIAC model? If there's some

Re: Using Field Sync about the Globe
There's been some reorganization of the website that I use of SwCADIII/LTspice publication. Could you folks let me know if the menu item Tools=>Sync Release works for you. It should work from anywhere

Re: Adding 3rd party Mosfet
Helmut, Yes you are correct, node 0 is global. Even if used in a subcircuit, it is global ground. You can't name the pin of a hierarchical symbol "0" and have that refer to the node "0" inside that

Steve, Thanks! Cool. Just the same, I don't think we should risk having a slogan like, "So easy to use even girls can use it." Yes, I we will be making it possible to have named plot setups and turn

Jon, Yes, this is something that's been needed for a long time. So I implemented it today. To use it make a symbol with prefix 'X'. Make ModelFile point to a library contianing subcircuits. Give the

Re: Adding 3rd party Mosfet
That's weird, the part is in an SOT-3 package w/ only 3 pins, but it seems that the 4th input is temperature??? I added this and commented out the Diode line and there are no errors now in simulation,

I've read through past messages, the SwCAD help and such and attempted to add a 3rd party model for the FDN304P. It seems to find the model fine now, but I get the error "Too few parameters for
