#21 Why delays are not synthesizsble in verilog or HDL | VLSI interview question

Описание: Why delays are not synthesizsble in verilog or in HDL has been explained in this verilog tutorial. Delays are ignored while designing digitial logic but delays are mostly used in testbench writing. Delays are not synthesizsble means synthesis tool can't convert a HDL code with delay into proper hardware.
