Before generating, check the blue warning messages to see if there are any potential issues with any components or their parameter settings in the system. Other than that, it's hard to diagnose the problem from what you've posted.

thanks for the reply. problem got fixed by setting up a environmental variable for IP_ROOTDIR to a $QUARTUS_DIR/ip path. but i dont know why i have to do this only when i introdruced esram IP. quartus running smoothly previously with all other IP's like pcie, emif, nios, msgdma, uart etc.,
