Hi,

Please see attached pspice code shared by one my customer. It is successfully compiled in TINA but shows error “Floating point division by zero”.

Same code is working perfectly in LTSpice.

Vinod,

This bug has been fixed. There're additional tests to be done before we can put it up for download. The schedule isn't firm but end of August is a good estimate.

Thanks,
JC
