specifyClock

Assign clock ports to cosimulation block or System object

Since R2022b

Syntax

specifyClock(cosimConfigObj,name)

specifyClock(__ ,Name=Value)

specifyClock(__ ,name,[])

Description

specifyClock(cosimConfigObj,name) explicitly maps the HDL port named name as a clock port in the generated block or System object™. The attributes for the clock inherit default values from the default_clock_definition row of the ClockPorts table.

specifyClock(__ ,Name=Value) sets properties using one or more name-value arguments in addition to the input arguments in the previous syntax. Unspecified arguments inherit the value from 'default_clock_definition'.

To change the default clock attributes, specify values for the 'default_clock_definition’.

specifyClock(__ ,name,[]) clears the definition for the clock port (or ports) specified in name. For example: specifyClock(c,'clk',[]) clears the definition for the clock named clk in the ClockPorts table.

Input Arguments

cosimConfigObj — Cosimulation configuration

cosimulationConfiguration object

Cosimulation configuration, specified as a cosimulationConfiguration object.

name — HDL clock port name

string | character vector | cell array

Name of the HDL port to map as a clock port in the generated HDL Cosimulation block or hdlverifier.HDLCosimulation System object, specified as a string or a character vector. For multiple clocks, specify a cell array of port names.

Example: clk

Example: {'clk1','clk2','clk3'}

Data Types: char | string

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: specifyClock(c,'clk1',Period=30) assigns the port named clk1 a period of 30 time units as defined by HDLTimeUnit.

Edge — Active clock edge

Rising (default) | Falling

Active clock edge, specified as Rising or Falling.

Period — Clock period

10 (default) | positive integer

Clock period, specified as a positive integer of HDLTimeUnit units.
