SystemSI & HSPICE engine - error

 Hi,

 I want to run my simulation deck aslo with HSPICE engine (Synopsys), but I get the error message:

"**error** failed to open S parameter file [.\dq_BBSckt_sp.s191p]."

The simulation with SPDSIM works fine and HSPICE in stand alone also works.

Does anyone has an idea?

many thanks

Tim
