This is how I'm doing it:

In the main part of the .tcl file I have this:

add_parameter CLOCK_SPEED INTEGER 1

set_parameter_property CLOCK_SPEED AFFECTS_GENERATION false

set_parameter_property CLOCK_SPEED HDL_PARAMETER false

set_parameter_property CLOCK_SPEED SYSTEM_INFO { CLOCK_RATE clock_reset }

In my elaboration callback I'm using this:

proc elaborate_me {} {

set_module_assignment embeddedsw.CMacro.CLOCK_FREQUENCY_IN_HZ [get_parameter_value CLOCK_SPEED]

}
