3.10.1.3. Base versus CvP Update Revisions in CvP Programming
The base.qsf file includes the following parameter settings:
set_global_assignment -name VERILOG_FILE system/synthesis/submodules/cvp_update_reset.v
set_global_assignment -name CVP_REVISION top
set_global_assignment -name ROUTING_BACK_ANNOTATION_FILE super_kernel_clock.rcf
The top.qsf file includes the following parameter settings:
set_global_assignment -name VERILOG_FILE system/synthesis/submodules/cvp_update_reset_zero.v
set_global_assignment -name REVISION_ TYPE CVP
set_global_assignment -name BASE_REVISION base
set_global_assignment -name INPUT_PERSONA persona/base.root_partition.personax -section_id Top
For both partitions, the Allow Multiple Personas parameter is set to On. This setting indicates that the board interface logic remains unchanged, but these partitions might change across different compilations. The acl_kernel_partition comprises of different kernel logic resulting from the compilation of the OpenCL kernel source code, as shown below:
In the case of a base revision compilation, invoking the export_persona -overwrite -partition Top Tcl command exports the persona/base.root_partition.personax file from the <path_to_s5_net>/hardware/s5_net/scripts/post_flow.tcl file. This .personax file is imported into all subsequent CvP update revision compilations. It preserves the placement and routing of all non-kernel-related logic so that CvP updates only change the logic residing in the kernel partition. Within the kernel partition, the kernel_system.qsys system is automatically generated at compilation time. It is a Platform Designer (Standard) subhierarchy of system.qsys. It contains one or more kernel IPs and wrapper logic to connect the kernel partition to the OpenCL board logic in board.qsys and the UDP logic in udp.qsys.
