Step 5: Hardware Validation - 2023.1 English

Hardware validation and interaction with the ChipScope debug cores can be done via XSDB.

1. Download the full PDI from a parent implementation and poll the GPIOs from the static region and rp1rm1. The GPIO from the static region is connected to a 32-bit down counter and rp1rm1 is connected to a 32-bit up counter.

   xsdb% mrd -force 0x80210000
   80210000:   8560E3C5
   

2. Read the GPIO in rp1rm1 to find the values counting up.

   xsdb% mrd -force 0x80220000
   80220000:   54FFC5A1
   
   xsdb% mrd -force 0x80220000
   80220000:   5B4B7E91
   

3. Observe the output of counters using ILAs in the static region and rp1rm1.
   • static region ILA
     
     
   • rp1rm1 ILA
     
     
4. Enable the Decouple signal before downloading the partial PDI for rp1rm2, which contains the count_down_vio module.

   xsdb% mwr -force 0x80200000 0x01
   xsdb% mrd -force 0x80200000
   80200000:   00000001
   

5. Download partial PDI for rp1rm2 (from either impl_std_child_1 or impl_abs_child_1) and release the Decouple signal.

   xsdb% mwr -force 0x80200000 0x00
   xsdb% mrd -force 0x80200000
   80200000:   00000000
   

6. Observe the Down counter in rp1rm2.

   xsdb% mrd -force 0x80220000
   80220000:   6B5A4A7D
   
   xsdb% mrd -force 0x80220000
   80220000:   60EF29C0
   

7. Observe the rp1rm2 Down counter using VIO in AMD Vivado™ Hardware Manager.
   
   
8. Enable the Decouple signal before downloading the partial PDI for rp1rm3.

   xsdb% mwr -force 0x80200000 0x01
   xsdb% mrd -force 0x80200000
   80200000:   00000001
   

9. Once rp1rm3 partial PDI is downloaded, disable the Decouple signal.

   xsdb% mwr -force 0x80200000 0x00
   xsdb% mrd -force 0x80200000
   80200000:   00000000
   

10. rp1rm3 has both up and down counters connected to two separate ILAs.

    xsdb% mrd -force 0x80220000
    80220000:   24776086
    
    xsdb% mrd -force 0x80220000
    80220000:   36D42755
    
    xsdb% mrd -force 0x80230000
    80230000:   A8B2F57F
    
    xsdb% mrd -force 0x80230000
    80230000:   9B470AEA
    

11. Observe the outputs in ILAs.
    • Up Counter in rp1rm3
      
      
    • Down Counter in rp1rm3
