Simulation of 555 timer

Question asked by t_clifford on Dec 11, 2014

Can anyone offer any help on trying to simulate a simple circuit using a 555 timer in Hyperlynx analog. I have downloaded a SPICE model, converted it to a HLA library, attached it to a symbol and used that to make a simple monostable. I have attached the original model,translated model and symbol.

When I try to run a transient analysis I get the following errors

..\..\sym\TLC555.mod(2): error -- ground is an illegal node in the definition of subcircuit tlc555.
..\..\sym\ibias.mod(2): error -- ground is an illegal node in the definition of subcircuit ibias.
..\..\sym\ibias.mod(6): error -- Error in DIABLO function diablo180.

 

Any ideas how to move forward?

 

I tried this with a FREE downloadable simulator using the downloaded model and was up and running within 2 mins without any problems.

 

Thanks
