Your email   Reduce XST Synthesis Warnings Type IDEA Status OPENED Hi John, Thanks for the serial divider routine. It works very well. I concur with Harold's findings. I was experimenting with the routine to reduce the number of XST synthesis warnings I got. I thought you might be interested in my notes Thanks, Bob S. ----------------------------------------------------- // Include S_PP in width declaration of grand_divisor to reduce synthesis warnings reg [M_PP+N_PP+R_PP-S_PP-2:0] grand_divisor; ----------------------------------------------------- // Include S_PP in width declaration of subtract_node to reduce synthesis warnings wire [M_PP+N_PP+R_PP-S_PP-1:0] subtract_node; // Subtract node has extra "sign" bit ----------------------------------------------------- // Include S_PP in width declaration of divisor_node to reduce synthesis warnings wire [M_PP+N_PP+R_PP-S_PP-2:0] divisor_node; // Shifted version of grand divisor ----------------------------------------------------- // Include S_PP in width declaration of quotient_reg to reduce synthesis warnings reg [M_PP+R_PP-S_PP-1:0] quotient_reg; // Used exclusively for the held output ----------------------------------------------------- // Include S_PP in width declaration of quotient_node to reduce synthesis warnings wire [M_PP+R_PP-S_PP-1:0] quotient_node; // Shifted version of quotient ----------------------------------------------------- // From: assign divisor_node = {1'b0,grand_divisor[M_PP+N_PP+R_PP-2:1]}; // To: assign divisor_node = {1'b0,grand_divisor[M_PP+N_PP+R_PP-S_PP-2:1]}; // From: if (~subtract_node[M_PP+N_PP+R_PP-1]) grand_dividend <= subtract_node; // To: if (~subtract_node[M_PP+N_PP+R_PP-S_PP-1]) grand_dividend <= subtract_node; // From: assign divisor_node = {1'b0,grand_divisor[M_PP+N_PP+R_PP-2:1]}; // To: assign divisor_node = {1'b0,grand_divisor[M_PP+N_PP+R_PP-S_PP-2:1]};   Stats Nobody is monitoring this item Progress   Submited date 03-Mar-2007 Submited by rasakamoto@i...   Assigned date Assigned to   Closed date Closed by Comments No comments yet..
