I'm trying to compile a (quite large) OpenCL design for Stratix 10, using Quartus v19.1. After a couple of hours of synthesis, the compiler fails by reporting the following error
Error (170019): Project requires 15090 ESBs, but the selected device can contain only 11721 ESBs Error: An error occurred during placement Error: Quartus Prime Fitter was unsuccessful. 2 errors, 71 warnings Error: Can't run the Timing Analyzer (quartus_sta) -- Fitter (quartus_fit) failed or was not run. Run the Fitter (quartus_fit) successfully before running the Timing Analyzer (create_timing_netlist). Error: Quartus Prime Timing Analyzer was unsuccessful. 1 error, 0 warnings Error: Quartus Fitter has failed! Breaking execution... Error (23035): Tcl error: Error (23031): Evaluation of Tcl script compile_script.tcl unsuccessful Error: Quartus Prime Compiler Database Interface was unsuccessful. 3 errors, 0 warnings Error: Compiler Error, not able to generate hardware
It's the first time that I encounter such kind of error. In the Intel OpenCL for FPGA manuals, there is no trace of "ESB".
Does someone have any clue to what this kind of error could be related?
Based on the error number: 170019, I found an information in link below:
In the error message stated that the design memory utilization is too large for the selected device. Hence, you would need to reduce the design.

I am glad that the error message had been clarified.
