[Qucs-help] Error simulating with SPICE -> QUCS
|

Hi, I've just found QUCS and I'm very impressed with it so far. I'm trying to import a manufacturer's SPICE model to use in my simulations, but I'm not having much joy. The macromodel I am attempting to use is shown below [1]. To use it in the SPICE -> QUCS translator, I have just stripped off the .SUBCKT and .ENDS commands (and added a .END), and used the QUCs dialog to connect up the nets listed as pins in the .SUBCKT statement. QUCS doesn't complain when reading the modified netlist. When attempting to run the simulation, however, I get an error: "line 46: syntax error, unexpected REAL, expecting Identifier or ScaleOrUnit" Looking at the generated netlist (below, [2]), this line appears to be where QUCS is using the translated component: L46: Sub:4301_RMS _net0 _net1 gnd _net2 _net3 RMSOut _net4 _net5 Type="n4301_RMS_spice_txt" I'm wondering if anybody can comment on what's going on here? I have attached the modified component SPICE netlist, and my simple test schematic. Many thanks, James.
