21.5.4 hdl_core_assign_bif_signal

Description

This Tcl command maps a bus interface signal definition name to an HDL core module port name.

This Tcl command maps bus interface signal definition name to an HDL core module port name. The command will fail if the HDL core name is not specified or is incorrect.

hdl_core_assign_bif_signal
-hdl_core_name { hdl_core_name } \
-bif_name { bus_interface_name } \
-bif_signal_name { bif_signal_name } \
-core_signal_name { core_signal_name }

Arguments

ParameterTypeDescription

hdl_core_name

string

Specify the HDL core name to which the bus interface signal needs to be added. This is a mandatory argument.

bif_name

string

Specify the bus interface name for which you want to map a core signal. This is a mandatory argument.

bif_signal_name

string

Specify the bus interface signal name that you want to map with the core signal name. This is a mandatory argument.

core_signal_name

string

Specify the core signal name for which you want to map the bus interface signal name. This is a mandatory argument.

Return TypeDescription
NoneNone

Error Codes

Error CodeDescription

None

Required parameter 'hdl_core_name' is missing.

None

Required parameter 'bif_name' is missing.

None

Parameter 'bus_interface' is missing or has invalid value.

None

Required parameter 'bif_signal_name' is missing.

None

Required parameter 'core_signal_name' is missing.

None

The bus interface 'BIF_name' has not been defined.

None

The bus interface signal 'SIGNAL NAME' has not been defined in the bus definition of the bus interface 'BIF name'.

None

Parameter 'param_name' is not defined. Valid command formatting is 'hdl_core_assign_bif_signal -hdl_core_name "hdl_core_name" -bif_name "BIF name" -bif_signal_name "BIf signal name" -core_signal_name "core signal name"'

Example

The following command adds 'HWRITE' bus interface signal to 'test_hdl_core' HDL core, maps with the 'myHRESULT' core signal name:

hdl_core_assign_bif_signal -hdl_core_name {test_hdl_core} \
-bif_name {BIF_1} -bif_signal_name {HWRITE} -core_signal_name {myHRESULT}
