Unable to map lookup tables to RAM in HDL coder
조회 수: 2 (최근 30일)
I am trying to reduce the utilization of lookup tables in my HDL code while using the Native Floating point library so, I enabled the option to 'map lookup tables to RAM' in the optimization settings. But even after selecting a synthesis tool, the RAM utilization is still at zero. Is there something I am missing that is not mentioned in the documentation?

Can you share a sample model with your configuration settings and desired synthesis results?
All floating point operator level customization options are available in the floating point panel or right-click HDL block options.
Currently 'Map lookup tables to RAM' is not plugged into the floating point operator specific customizations. I will communicate this request to the team.
Please review some sample synthesis metrics here Synthesis Benchmark of Common Native Floating Point Operators. You can easily regenerate the latest synthesis results using this example for your choice of synthesis tool, data types, frequency, fpga device, power settings.
