Why do I get the different available resource when compiling the same OpenCL™ design with different versions of FPGA OpenCL™ SDK?
Description
When you compile the same OpenCL™ design with different versions of FPGA OpenCL™ SDK on the same Arria® 10 GX FPGA Development Kit, you may get different “Available Resource” from the generated report.html file. The detail is as follows.
|
Available Resource(ALUTs) | |
|
V18.1.0 V18.1.2 V19.1.0 V19.1.2 V19.1.3 |
788,860 788,860 854,400 854,400 854,400 |
Resolution
Interpret the "Available resource" in the report.html file based on the version.
In versions 18.1.2 and older, the "Available Resource" in the report.html file describes the amount of resources remaining in the device after the resources used by the BSP are subtracted. This number will always be less than the total resources reported in the device datasheet.
In version 19.1.0 and newer, the "Available Resource" in the report.html file describes the total resources available in the device. The resources used by the BSP are not subtracted. This number should match the total resources reported in the device datasheet.
