Step 6: Creating Revisions
The PR design flow uses the project revisions feature in the Intel® Quartus® Prime software. Your initial design is the base revision, where you define the static region boundaries and reconfigurable regions on the FPGA.
From the base revision, you create multiple revisions. These revisions contain the different implementations for the PR regions. However, all PR implementation revisions use the same top-level placement and routing results from the base revision.
To compile a PR design, you must create a PR implementation revision for each persona. In addition, you must specify the Partial Reconfiguration - Base or Partial Reconfiguration - Persona Implementation revision type for each of the revisions.
The following table lists the revision name and type for each revision you create:
| Revision Name | Revision Type |
|---|---|
| blinking_led.qsf | Partial Reconfiguration - Base |
| hpr_child_default.qsf | Partial Reconfiguration - Persona Implementation |
| hpr_child_slow.qsf | Partial Reconfiguration - Persona Implementation |
| hpr_child_empty.qsf | Partial Reconfiguration - Persona Implementation |
| hpr_parent_slow_child_default.qsf | Partial Reconfiguration - Persona Implementation |
| hpr_parent_slow_child_slow.qsf | Partial Reconfiguration - Persona Implementation |
| Revision Name | Parent Persona Behavior | Child Persona Behavior |
|---|---|---|
| hpr_child_default.qsf | Fast Blinking | Fast Blinking |
| hpr_child_slow.qsf | Fast Blinking | Slow Blinking |
| hpr_child_empty.qsf | Fast Blinking | No Blinking (Always ON) |
| hpr_parent_slow_child_default.qsf | Slow Blinking | Fast Blinking |
| hpr_parent_slow_child_slow.qsf | Slow Blinking | Slow Blinking |
