ipxact ports enclosed in a ifdef macro

[Khushi]

Hello

Is it possible in ipxact to describe ports which are enclosed in ifdef macro. For example

module m(
    input [31:0] addr,
    output [31:0] data,
`ifdef ABC
	in abc_in,
	out abc_out,
`endif
);
endmodule

If yes, how to describe such ports in ipxact. If not, then what is the recommended way to model such RTL IP

Thank you

Hi Kushi,

The idea of 1685-2014 is to support this with the isPresent element. This functionality has been removed in 1685-2022 but it can be supported with the Accellera Vendor Extensions for 1685-2022. Please see https://accellera.org/images/downloads/standards/ip-xact/1685-2022-VE-1.0-Specification.zip

My own opinion is that this RTL code describes 2 different IPs (one with ABC defined and one with ABC undefined) and that you should create two different IP-XACT components to describe those two different RTL IPs. This is an example of a configurable IP that can be used to create two configured IPs. The configured IPs are supported by the IP-XACT component schema. The configurable IP must be handled with a generator (e.g. using TGI). The generator takes the value of ABC as input and generates the IP-XACT component for the configured IP.

Best regards,
