Slide 26 of 43
Notes:
The example here uses the IF-scheme GENERATE statement to make a modification to the and_gate array such that the seventh gate of the array will be an or_gate.
Another example use of the IF-scheme GENERATE is in the conditional execution of timing checks. Timing checks can be incorporated inside a GENERATE IF-scheme. For example, the following statement can be used:
Check_time : IF TimingChecksOn GENERATE
This allows the boolean variable TimingChecksOn to enable timing checks by generating the appropriate concurrent VHDL statements in the description. This parameter can be set in a package or passed as a generic and can improve simulation speed by shutting off this computational section.
