From the Verilog-AMS Language Reference Manual
Code:`include "disciplines.va"
`include "constants.va"
module diffPair (c1, b1, e, b2, c2);
electrical c1, b1, e, b2, c2;
vertNPN Q1 (c1, b1, e);
vertNPN Q2 (.c(c2), .b(b2), .e(e));
endmodule
Where vertNPN is a spice model line. I assume this code is can not compile. How to fix this code?
