I generated an SOPC system using the custom 16 bit SRAM controller sram_256Kx16bit_hw.tcl

result:the SRAM address width was generated as 19 bits wide although the IDT71V416 (ISSI IS61WV25616BLL) has only 18 bits

as seen below from the NIOSII_system module definition of the address to the external SRAM

output [ 18: 0] address_to_the_ext_sram_256Kx16bit;

what is the best action to take to connect the 18 bit SRAM address lines

thanks
