E310, RFNoC OFDM Sync block error

[Louis Jung]

Dear all,

I always appreciate your help.

I’m trying to run Wi-Fi OFDM receiver in E310.

However, when I tried to build custom fpga image with fft, window, and 
schmidl_cox blocks, it always fails with the error:
''ERROR: [Place 30-640] Place Check : This design requires more Slice LUTs 
cells than are available in the target device. This design requires 62507 of 
such cell types but only 53200 compatible sites are available in the target 
device. Please analyze your synthesis results and constraints to ensure the 
design is mapped to Xilinx primitives as expected. If so, please consider 
targeting a larger device. Please set tcl parameter 
"drc.disableLUTOverUtilError" to 1 to change this error to warning.”

Is it infeasible in E310 or I misconfigured something?

Any guess?

Best,

Jinhwan
