Title: Inverter Design with TSMC cmos18 techlib
Post by Fei on Aug 4^th, 2004, 1:33pm

Hi,

I tried to simulate an inverter which is design with tsmc coms0.18 technology. The input is voltage pulse source. The simulator I chose was spectre. The results look strange (the output is high all the time no matter what the input voltage is?)

I am wondering if I should choose any other simulator insteasd of spectre?

Thanks

Fei

Did you remember to wire the power and ground up properly?

Just changing the simulator is unlikely to help - it may possibly be a design kit/model problem, but much more likely is a circuit configuration problem, in which case you'll have trouble no matter what the simulator you use.

Andrew.

I guess that is an error in your netlist. :)

You should check the netlist first when an error comes up. I think more than 90% curious phenomenan occuring in simulation is due to wrong design. :)
