Tcl command to change the output clock frequency of the PLL

Hi, 

 

I am using a PLL in my platform designer design. I want to change one of the output clock frequency of the PLL using tcl command.

What is the tcl command to change the output clock frequency of the PLL ?

I am using Intel Quartus Pro 23.3

 

Note: I use the below command to change the clock frequency in Quartus Standard.

set_instance_parameter_value iopll_0 {gui_output_clock_frequency1} {125.000000}

The same command does not work in Quartus pro.

 

Any suggestions on this issue?

 

Thanks

Unfortunately, instance parameters are no longer supported in Pro. Therefore, the instance parameter TCL script flow used in Quartus Standard may not be applicable in Pro.

 

Instead , please use "Parameterizing an Instantiated IP Core after save_system Command"
