smartpower_set_domain_frequency

Sets the frequency of a domain in megahertz (MHz).

smartpower_set_domain_frequency -domain_type {value} -domain_name {domain_name} -clock_freq {value} -data_freq {value} -pin_freq {value}

Arguments

-domain_type {value}

Specifies the type of domain to set. The following table shows the acceptable values for this argument:

Value	Description
clock	The domain is a clock domain
set	The domain is a set domain

-domain_name {domain_name}

Specifies the name of the domain for which the frequency will be set.

-clock_freq {value}

Specifies the clock frequency in megahertz (MHz), which can be any positive decimal number. This argument is available only for a clock domain.

-data_freq {value}

Specifies the data frequency in megahertz (MHz), which can be any positive decimal number. This argument is available only for a clock domain.

-pin_freq {value}

Specifies the value of the pin frequency in megahertz (MHz), which can be any positive decimal number, which can be any positive decimal number. This argument is available only for a set domain.

Supported Families

Fusion, ProASIC3/E, ProASICPLUS, Axcelerator, and ProASIC

Notes

The domain type must be either “clock” or “set.”
The domain name must be the name of an existing domain.
The clock frequency must be a positive decimal number. Specifying the unit as part of the frequency value is optional. You must enter a space between the frequency value and the unit. You set the clock frequency only for clock domains.
The data frequency must be a positive decimal number. Specifying the unit as part of the data frequency value is optional. You must enter a space between the data frequency value and the unit.

Exceptions

None

Examples

The following example sets the clock and data frequency of a clock domain:

smartpower_set_domain_frequency –domain_type {clock} –domain_name {clk1} –clock_freq {32} or {30 MHZ} –data_freq {3} or {3 Mhz}

The following example sets the data frequency of a set domain:
