In reply to verif_learner:
Hello,
Probably Dave will answer this with a more comprehensive explanation, but the main problem you face with parameters is that each agent with a different parameter represents a specialisation, then you face problems for example when casting or using configdb for example the following code will be illegal
function build_phase();
agent_m=new[2];
agent_m[0]=agent#(32)::type_id::create("agent", this)
agent_m[1]=agent#(64)::type_id::create("agent", this)
I previous example you cannot store these agents in a single array since each specialization is a unique type thus generating issues in maintaining the code and extending it.
Probably there are more good reasons lets wait for Dave’s response :)
HTH,
