Developer can make the Vivado design changes in the ext_bdc_vma.bd after importing VMA except inside the hierarchy (VitisRegion.v). You can view connnection between HLS kernels to AIE inside the VitisRegion hierarchy. Refer to UG1393 to understand the design guidelines and limitations under the section “Vitis Export Flow Guidelines and Limitations”.
NOTE: Any changes related to VitisRegion hierarchy in ext_bdc_vma.bd can only be done through Vitis. It is read-only in Vivado.
Based on the Vivado design changes affecting the PLIO interface or not, we are covering the two use cases as discussed. In step-5, we are covering the use-case 1, where the design changes are not affecting the PLIO interface. To do the Vivado design changes affecting the PLIO interface refer to -[Use Case 2: Vivado design changes affecting the PLIO boundary]
