Modifying an Existing Persona

You can change an existing persona, even after fully compiling the base revision.

For example, to cause the blinking_led_child_slow persona to blink even slower:

  1. In the blinking_led_child_slow.sv file, modify the COUNTER_TAP parameter from 27 to 28.
  2. To re-synthesize and re-implement this persona, you must recompile all the synthesis-only revisions and implementation revisions affected by the change. Modify the setup.tcl script to include the following lines: 
    define_project blinking_led

define_base_revision blinking_led

define_pr_impl_partition -impl_rev_name blinking_led_pr_bravo \
        -partition_name pr_partition \
        -source_rev_name blinking_led_child_slow \
        -source_partition root_partition \
        -source_snapshot synthesized

define_pr_impl_partition -impl_rev_name blinking_led_pr_bravo \
        -partition_name pr_parent_partition \
        -source_rev_name blinking_led_pr_alpha \
        -source_partition pr_parent_partition \
        -source_snapshot final

define_pr_impl_partition -impl_rev_name blinking_led_pr_delta \
        -partition_name pr_partition \
        -source_rev_name blinking_led_child_slow \
        -source_partition root_partition \
        -source_snapshot synthesized

define_pr_impl_partition -impl_rev_name blinking_led_pr_delta \
        -partition_name pr_parent_partition \
        -source_rev_name blinking_led_pr_delta \
        -source_partition pr_parent_partition \
        -source_snapshot final
    Note: When defining the pr_parent_parition for blinking_led_pr_delta revision, you import the final snapshot of that persona for implementation. As a result, the implementation of the parent partition logic remains the same, while modifying and implementing the corresponding child partition.
    This command re-synthesizes the blinking_led_child_slow synthesis revision, and then runs the PR implementation compile using blinking_led_pr_bravo.
  3. To perform compilation of the synthesis-only revisions, run the following command: 
    quartus_sh -t a10_hier_partial_reconfig/flow.tcl -setup_script \
        a10_hier_partial_reconfig/setup.tcl -all_syn

    This command does not recompile the base revision.

  4. To perform compilation of the implementation revisions, run the following command: 
    quartus_sh -t a10_hier_partial_reconfig/flow.tcl -setup_script \
        a10_hier_partial_reconfig/setup.tcl -all_impl

    This command does not recompile the base revision.

  5. Follow the steps in Step 10: Programming the Board to program the resulting RBF file into the FPGA.
Note: To avoid running the entire flow for every revision, define the synthesis-only revisions and implementation revisions in the setup.tcl script, and run the script.
