Glue Logics in IPXACT
Bhargav posted a topic in IP-XACT DiscussionHi, I have a question in how glue logics between two or more ports get represented in IPXACT. Lets say there is an ADHOC Connection between, PORT A of instance A and PORT B of instance B, in such a way that, PORTB is connected as 32'habcd ^ PORTA Like, Instance A: output port A Instance B: input port B Now, on Top file, In SV , I have following glue logic. module Top module A instance A( .A(A) ) module B instance B( .B(32'habcd ^ A) //32'habcd XOR with A ) endmodule Now, in adHoc connection,we genrally, represent two connections with just internalportreferences. How does such glue logics get represented? Thanks in advance.
Previous versions of IPXACT has attributes, 'left' and 'right' inside internalPortReference element of adHocConnection in design IPXACT as shown in the following 4 lines of xml. <spirit:adHocConnection> <spirit:name>....</spirit:name> <spirit:internalPortReference spirit:ComponentRef = "..." spirit:PortRef=".." spirit:left="..." spirit:right="...."/> </spirit:adHocConnection> These attributes basically say that which vector range of port from one component is mapped to another (I assume) However, the same IPXACT with latest schema, while validation gives schema error stating, attribute right/left is not allowed. Even the latest xsd files available with accellera doesn't define these attributes.There must be some means how currently, these multibit adHocConnections are mapped between two components inside an IPXACT-design. What could be the solution for this?
