Ideas for integrating a full-custom designed layout with a semi-custom designed microprocessor.

Hello,

I have verilog codes - (of a microprocessor design.), tell me a way to do the logic and physical synthesis which satisfies the below conditions:

I created register file/ RAM layout in cadence virtuoso. These register files are created with a novel architecture, and I want to add these in to the microprocessor design which is mentioned before.

Please note that I am not creating memory or a RAM for the microprocessor in verilog codes. I am creating a custom-designed layout in cadence virtuoso to create the RAM.

I want to know how to integrate the two design layouts together. Any suggestion/ ideas are welcome.

1 easy method which comes to mind : DO the logic synthesis in Cadence RTL Compiler in regular fashion and then, while creating the layouts in SOC Encounter, leave a seperate space in the floorplan for the custom designed layout. So that, it can be attached later.

Does this idea work? Kindly help me with an optimized design flow solution . please!!!
