A<=0;
if (sel==0)

Honored ContributorOkay, so that simply means:
1) Assignment in different 'always' blocks --> they are evaluated in parallel, resulting in multiple driver error 2) Assignment in the same 'always' block --> they are evaluated in sequential, where it will reset initially before going into a MUX
