Creating new IsSpice4 Models, and Conversion to IsSpice4 from Pspice
If you have any of Intusoft's ICAP/4Rx offerings, then you do not have Intusoft's Library Manager Tool. Therefore you must follow steps 1-4 below. Otherwise, click on and follow Intusoft's IsSpice4 User's Guide appendix D and E.
Pspice syntax is slightly different from IsSpice4 syntax, which closely
follows Berkley SPICE3F.5 syntax.
Model Creation (ICAP/4 Rx users):
2) After the ***** line marking where your part begins, you will be adding a *SRC= line to link to SpiceNet's part browser. The text on this line matches what is shown in the part browser and will be searched for when you click on the “find” button in the part browser.
Note: The combined length of the Part Number and Notes fields should be no longer than 30 characters. The Part Type and SubType each should be no longer than 13 characters. The SubCkt field MUST be unique and match the model name on the .subckt line below. Spaces, or !@#$%^&* characters, are NOT allowed for the SubCkt field.
3) After the *SRC= line you will be adding a *SYM= line to point to which symbol you want your part to use. You can browse the part browser for an existing symbol and type its name here, to simply use the same symbol as an equivalent part. SpiceNet also includes generic box symbols so you can use *SYM=##pin where ## is a number between 01 and 32. The number of pins on your symbol must match the number of nodes on your subckt line.
4) Finally, place the saved.lib file with your added part netlist to the c:\spice8\pr folder and run MakeDB. MakeDB can be run from the ICAP_4 Program Files menu, or by selecting File > Update Part Database from within SpiceNet.
