Hello,
I’m having issues using a model created using the THS4551.lib file available from TI. I receive these errors in the console:
Error in line .model _w1•x_w1•x3 iswitch roff•x_w1•x3=10e6 ron•x_w1•x3=1 ioff•x_w1•x3=5e-6 ion•x_w1•x3=7e-6
Unknown model type "ISWITCH" - ignored.
Error in line .model _w2•x_w2•x3 iswitch roff•x_w2•x3=10e6 ron•x_w2•x3=1 ioff•x_w2•x3=5e-6 ion•x_w2•x3=7e-6
Unknown model type "ISWITCH" - ignored.
Didn't find a model for "_W1•X_W1•X3" -- defaults assumed.
Didn't find a model for "_W2•X_W2•X3" -- defaults assumed.
Fatal error: Either both of Ion and Ioff or It and Ih must be specified for switch model W
Does anyone have any idea how to resolve these errors? Thanks!
Here is the contents of the .lib file:
