9. Component Target Frequency

You can specify component target frequency either in the i++ command by specifying the --clock option.

For details about the --clock option, see Command Options Affecting Compiling.

The --clock option applies to all components compiled with the invocation of the i++ command that contains the --clock option.


Setting the target fMAX determines the pipelining effort at the compilation stage. Compiling with Quartus Prime software reports the achievable fMAX value for your components. This value is often different from the value you specified.

You can lower the --clock value to reduce the latency of your design at the expense of reducing the fMAX v of your component.
