What's the difference between '#5 a = b;' and 'a = #5 b;'?

#5 a=b

What's the difference between '#5 a = b;' and 'a = #5 b;'?

#5 a = b;

and

a = #5 b;

 

[wufei]

difference of 5

how can i verify the difference?

difference between 5a and 5b

Simulate in Modelsim and check..!!!!

# 5 a = b ; Its Inter assignment delay

a= # 5 b ; Its Intra assignment delay

Intra-assignment delays block assignment but not evaluation
Inter-assignment delays block both evaluation and assignment

For details refer any verilog book.

thanks
but it seems that simulations of these two assignments in Modelsim have the same results...
