Slide 41 of 93
Notes:
The REJECT construct is a new feature to VHDL introduced in the VHDL 1076-1993 standard. The REJECT construct can only be used with the keyword INERTIAL to include a time parameter that specifies the input pulse width constraint.
Prior to this, a description for such a gate would have needed the use of an intermediate signal with the appropriate inertial delay followed by an assignment of this intermediate signal’s value to the actual output via a transport delay.
