2 Creating a Design
A complete design comprises sub-systems published in terms of block elements. Each block element is instantiated in a top-level module. The top-level module is floorplanned into separation regions for each sub-system block and overlapping IRS region connecting the blocks. These IRS regions must be isolated physically from other IRS regions. Select the Enable Design Separation Methodology check box in the Design flow settings on the Project settings page as shown in following figure. The design is then run through a layout, followed by the timing closure of your design.
For more information about creating your design, see the Microchip Design Separation Methodology Guide.
