Hi,

I need to make some connections based upon randomixed value of a variable.

I am using OVM environment.

1) Can i do this in TOP module ???

2) How can i do this as the variable will take its randomized value in class and i can not use class data in declarative context.??

Can anyone help me out in this ???

Can you explain what the choices you want to randomize are? i.e. give an example of one connection that is not random, then show what you want the alternative to be.
 

In my top module , i have say

Curent implementation:-

module_tx inst_1 (.a (b));

module_rx inst_1 (.c (b));

assign rx_signal_1 = tx_signal_1;
assign rx_signal_1 = b ;

What i want is... say i have a variable "temp" which can produces 4 values on randomization :- 1,2,3,4

So, when temp =1 , i want only this connection :- assign rx_signal_1 = tx_signal_1;

when temp =2 , i want only this connection :- module_rx inst_1 (.c (b)); & module_tx inst_1 (.a (b));

when temp=3 , i want only this connection :- assign rx_signal_1 = b; & module_tx inst_1 (.a (b));
