Define elapsed time in clock cycles between deassertion of reset and assertion of clock enable
N
(integer number of clock cycles)
Default: 1
The TestBenchClockEnableDelay
property specifies a delay time
N
, expressed in base-rate clock cycles ( the default value is
1) elapsed between the time the reset signal is deasserted and the time the clock enable
signal is first asserted. TestBenchClockEnableDelay
works in
conjunction with the HoldTime
property; after deassertion of reset, the
clock enable goes high after a delay of N
base-rate clock cycles
plus the delay specified by HoldTime
.
In the figure below, the reset signal (active-high) deasserts after the interval
labelled Hold Time
. The clock enable asserts after a further interval
labelled Clock enable delay
.
