EL2 Memory Interface ​Synthesis Compatibility

[nstewart-amd]

At the integration wrapper level the module containing the ICCM/DCCM SRAM’s is implemented with the el2_mem_if interface and modport: top​

The //mytopdesign// module does not define a modport for the el2_mem_if​
This leads to compile issues through Design Compiler.​

Ie. ​
Warning: In design 'mytopdesign_ccm_sram_wrap_I_el2_mem_export_el2_mem_if_top_', output port 'el2_mem_export.dccm_bank_dout[0][0]' is driven from the outside. (LINT-64)​

One solution that worked on our side:​
Explicitly define two interface buses on mytopdesign with “swerv_iccm/swerve_dccm” modports​
Pushing these two interfaces all the way down to the el2_lsu
