signal 9 error - signal 9 error I am using Quartus Prime Pro 21.2 .While doing full compilation in fitter I got the error Error(20549): Current module quartus_fit was unexpectedly terminated by signal 9. This may be because some system resource has been exhausted, or quartus_fit performed an illegal operation. You can view system resource requirements on the System and Software Requirements page of the Intel FPGA website ( https://fpgasoftware.intel.com/requirements/ ). I have to store 1056 values each 9 bits.I am using the device AGFB027R24C2E1V. How to resolve this error? Replies: Re: signal 9 error The maximum values can be stored in 9 bits is 512. Thus, you cannot store 1056 values in 9 bits. You may try to change your bit to 11 bits.
