#25 Difference between ALWAYS and INITIAL Block in verilog || VLSI interview question

Описание: Always blocks are called procedural block and it's a very useful constructs in verilog design. This tutorial explains how multiple always blocks are handled in verilog to avoid multi driver error in verilog.


Initial blocks are called procedural block and it's a very useful constructs in verilog design. This tutorial explains how initial blocks are handled in verilog and how initial blocks can be used effectively in verilog HDL.
