Patch created on May 07 2019
Patch Case#: 1409342244
//****************************************************************

Description:

This patch provides a workaround for configuration errors seen on Intel Stratix 10 devices during FPGA core configuration from HPS (HPS first boot flow), when Phase 1 and Phase 2 configuration bitstreams are created from designs with different FPGA IO assignments. 

After installation of this patch follow the steps below
1. Set the following Quartus INI in a text file called quartus.ini located in the project directory or the Quartus installation directory 
   asm_constant_hpsio_hash = on 
2. Run a full compile in Quartus Prime Pro including the Assember for the both phase 1 and phase 2 projects. This will re-generate .sof files

3. Follow normal flows to generate additional programing files,  ensuring that the conversion tools (quartus_cpf / progrmaming file generator) are launched from a directly containing the INI file. (Open a command prompt and navigate to the directory containing the .ini file, then launch the conversion tools) 

Note: 
- The quartus_cpf tool reports if a quartus.ini file has been located and is in use. 
	"Info: Using INI file xxxx/yyy/quartus.ini"
- If the patch and INI are being used the HPS IO hash printed during conversion should be of the form:  
	"Info (19848): HPS IO hash is 0123456789ABCDEF001122334455667788889999AAAABBBBCCCCDDDDEEEEFFFF"


Caution - You must either have previously installed the
          Quartus Prime 19.1 software or must
          install the Quartus Prime 19.1 software
          before installing this patch. Otherwise, the patch will
          not be installed correctly and the Quartus Prime
          software will not run properly.
