Each initial and always block executes concurrently in every module at the start of the simulation. The Initial Block Example WebbThere are two kinds of assignments which can be used inside the always block i.e. blocking and non-blocking assignments. The ‘=’ sign is used in blocking assignment; whereas the ‘<=’ is used for non-blocking assignment as shown in Listing 4.1 and Listing 4.2. Both the listings are exactly same expect the assignment signs at lines 13-14. Webb13 jan. 2014 · In synthesizeable Verilog, it is possible to use an assign statement inside of a generate block. All a generate block does is mimic multiple instants. Be careful though, because just like a for loop, it could be very big space-wise. You can use assign in generate statment, it is quite common to help parameterise the hook up modules. how far is 1200 nautical miles in miles
