Description
Creates a virtual clock for the current solution.
The command can be executed only in the context of an active solution. The clock period is a constraint that drives optimization (chaining as many operations as feasible in the given clock period).
C and C++ designs support only a single clock.
Syntax
create_clock -period <number> [OPTIONS]Options
-
-name <string> - Specifies the clock name. If no name is given, a default name is used.
-
-period <number> - Specifies the clock period in ns or MHz.
- If no units are specified, ns is assumed.
- If no period is specified, a default period of 10 ns is used.
Examples
Species a clock period of 50
ns:
create_clock -period 50Uses the default name and period of 10 ns to specify the
clock:
create_clockSpecifies clock frequency in
MHz:
create_clock -period 100MHz
