Signaling and Clocking Protocols
Parameters
Table 3-3 provides a description of the configuration parameters for the ClockDivider
component.

Description
Type
Allowed
value
Default
value
mul clock rate multiplier integer uint_32 1
div clock rate divider integer uint_32 1
Registers
The ClockDivider component has no registers.
Debug features
The ClockDivider component has no debug features.
Verification and testing
The ClockDivider component was tested as part of the VE example system by running VE test
suites and by booting operating systems.
Performance
The ClockDivider component does not normally incur a runtime performance cost. However,
reprogramming the clock rate causes all related clocks and timers to be recalculated.
Library dependencies
The ClockDivider component has no dependencies on external libraries.
3.3.3 ClockTimer component
The ClockTimer component provides a mechanism for other components to schedule a callback
after a number of ticks at a given ClockSignal rate.
There is an example use of the ClockTimer component in the CPTimers.lisa example component
in the System Canvas Model Library. See the %PVLIB_HOME%\examples\Common\LISA directory of
your Fast Models distribution. On Linux, use the $PVLIB_HOME/examples/Common/LISA directory
instead.
Figure 3-3 shows a view of the component in System Canvas.
This component is written in C++.
