| 20.4 |  
       Migrating a design using a P-tile  Avalon®  Streaming or  Avalon®  Memory-mapped IP from an earlier  Quartus® Prime version to the 20.4 version requires an IP upgrade.  |  
       You must regenerate any design using a P-tile  Avalon®  Streaming or  Avalon®  Memory-mapped IP when moving from an earlier  Quartus® Prime version to the 20.4 version.  |  
      
 
       
       | Parameters to enable independent resets for the ports in the bifurcated x8x8 Endpoint mode have been added to the IP Parameter Editor of the P-tile  Avalon®  Streaming and  Avalon®  Memory-mapped IPs.  |  
       Each port in the bifurcated x8x8 Endpoint mode can be reset independently of the other port. Two new reset signals (p0_pld_clrpcs_n, p1_pld_clrpcs_n) are exported to the top-level block symbol when independent resets are enabled. These signals can be assigned to GPIO pins. Contact your local Field Applications Engineer (FAE) for more details.  |  
      
 
       
       | The parameter to enable the MSI-X capability has been removed from the IP Parameter Editor when the P-tile  Avalon®  Streaming or  Avalon®  Memory-mapped IP is in Root Port (RP) mode.  |  
       The P-tile  Avalon®  Streaming or  Avalon®  Memory-mapped IP is not required to support sending MSI-X in RP mode.  |  
      
 
       
       | The parameter to enable extended tag support has been added to the IP Parameter Editor of the P-tile Avalon Streaming IP. |  
       The P-tile  Avalon®  Streaming IP can support extended tag in this release.  |  
      
 
       
       | Options to set acceptable Power Management latencies for Endpoints were added to the IP Parameter Editor of the P-tile  Avalon®  Memory-mapped IP.  |  
       L0s and L1s acceptable latencies can now be configured in the IP Parameter Editor of the P-tile  Avalon®  Memory-mapped IP in Endpoint mode.  |  
      
 
       
       | Options to configure the VSEC parameters in Endpoint mode were added to the IP Parameter Editor of the P-tile  Avalon®  Memory-mapped IP.  |  
       VSEC parameters can now be configured in the IP Parameter Editor of the P-tile  Avalon®  Memory-mapped IP in Endpoint mode.  |  
      
 
       
       | The parameter to enable VirtIO and SR-IOV capabilities have been removed from the IP Parameter Editor when the P-tile  Avalon®  Streaming IP is in Root Port (RP) mode.  |  
       The P-tile  Avalon®  Streaming IP is not required to support VirtIO or SR-IOV in RP mode.  |  
      
 
       
       | Options for BAR configuration, Multi-function and SR-IOV support have been removed from the IP Parameter Editor when the P-tile  Avalon®  Streaming IP is in TLP Bypass mode.  |  
       The P-tile  Avalon®  Streaming IP is not required to support these features in TLP Bypass mode.  |  
      
 
       
       | Options for Multi-function and SR-IOV support support are now visible for Port 1 when the P-tile  Avalon®  Streaming IP is in a bifurcated mode.  |  
       Multi-function and SR-IOV support can be enabled for Port 1 when the P-tile  Avalon®  Streaming IP is in a bifurcated mode.  |  
      
 
       
       | The IP Parameter Editor response time has been improved for the P-tile  Avalon®  Streaming IP.  |  
       The turnaround time after each user input in the IP Parameter Editor is significantly reduced for the P-tile  Avalon®  Streaming IP in this release.  |
