    Simulation of 555 timer

    t_clifford

      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
