A parameter with an undesired value can lead to both very obvious errors (mismatch in size of a wire to a port) or to very subtle errors (e.g. a parameter used to count a number of clock cycles before reporting an error is set too large to ever get triggered). For this reason, it...
(out, pin) ; // Declares two ports output out ; input pin ; voltage out, pin ; // Declares port as output // Declares port as input // Declares discipline of ports parameter real gain = 2.0 ; analog V(out) <+ gain * V(pin) ; endmodule Note: Port direction must be declared ...
As we can see from this, when we want to pass a parameter by reference rather than value then we simply replace the input keyword with the ref keyword. We use the ref keyword for each argument which we want to pass by reference. This means that we can use a mixture of passing by va...

Similar to keywords, declared variables of typeinput,output,inout,wire,reg, andparameterare colorized when the definitions are found. Otherwise they will appear in plain text white. SeeBuildHoverItems(string s)for the state machine logic that parses the data looking for variables. Note that the...
