Just out of curiousity..

if you say make a state machine will a full sensitivity.. does it really matter if you make your assignments either blocking or non-blocking?

and if it doesn't.. what is your personal preference?

I think it does not matter.
But I used to use non-blocking assinmet.
 

for combinational logic usually blocking assignments are used...though non blocking assignments will work properly..
 

if you are doing a continious assignment then you should do blocking. If you are working in a clock domain then do non blocking.
 

It is preferable to use blocking assignments as they generate appropriate logic as compared to non-blocking assignments.as I found in synthesis book by J.Bhaskar. which explains the logic generation from blocking and non-blocking assignment.
although it doesn't matter when your application works well within constraints.
 

I prefer that combinational logic using continious assignment and sequence logic using non-blocking assignment.
