Description

This Tcl command removes the synthesis attribute from the specified SmartDesign module.

sd_remove_comp_synth_attr -sd_name {SmartDesign component name} \
                          [-attr_name {synthesis attribute name}]


Parameter	Type	Description
sd_name	string	This argument is used to specify the name of the SmartDesign module from which the synthesis attribute is removed. This is a mandatory argument.
attr_name	string	Synthesis attribute to be deleted. If the argument is not specified, all the attributes are deleted.

None	None


Error Code	Description
None	Failed to remove the synthesis attribute 'syn_no_compile_point' from the component 'top'. This attribute does not exist.
None	Parameter 'attr_name' has illegal value.
None	The component 'sd_name' does not exist.
None	Parameter 'sd_name' has illegal value.
None	Required parameter 'sd_name' is missing.
None	Parameter 'param_name' is not defined. Valid command formatting is 'sd_remove_comp_synth_attr -sd_name "sd_name" [-attr_name "attr_name"]'.

This example removes the "syn_no_compile_point" attribute of the "top" component.

sd_remove_comp_synth_attr -sd_name {top} \
                          -attr_name {syn_no_compile_point}
