Best Practices and Common Mistakes
 

Best Practices
 

  • Use #delay only in testbenches, never in synthesizable RTL
     

  • Use @(posedge clk) for synchronous RTL design
     

  • Use wait for level-sensitive synchronization in testbenches
     

  • Always use @(*) for combinational logic, not explicit lists
     

  • Use named events for complex testbench coordination
     

Common Mistake #1: Missing @ in Testbench
