Which IP Category is recommended for the Math Square Root function?
- 4 years ago
Hi Shriram,
However, I'm having issues with timing and I/O chip placement. Any suggestions?
Timing issues had been resolved by sdc file. I reattached the file below with new sdc as I further remove the unconstraint paths. As for I/O chip placement you may have to open a new thread in FPGA, SoC, And CPLD Boards And Kits forum for better confirmations.
How to calculate / how to find speed grade around for a clock in MHz ?
The clock frequency can be checked in timing analyzer by report clock. As for speed grade you can refer to this document https://my.mouser.com/datasheet/2/612/s10_datasheet-1652682.pdf Core Performance Specifications section (page 28).
How to determine Maximum combined path delay in ns ?
Can be checked in timing analyzer as well by report timing.
Hope it helps. Thanks.
Best Regards,
Sheng

Hi,
FPGA - Can refer https://www.intel.com/content/www/us/en/docs/programmable/683339/21-3-19-1-1/fixed-point-ips-device-family-support.html for device support list.
I/O Chip - Do you mean processor?
SDC - Do you mean Scalable Dataframe Compiler or Synopsys Design Constraints?

Hi Sheng
I am using Intel® Stratix® 10.
I/O Chip is the 1SG280LN2F43E1VG
SDC mean Synopsys Design Constraints
I can successfully compile the design with above attached files.
However, I'm having issues with timing and I/O chip placement. Any suggestions?
