Honored ContributorIn the last process you're using the vector Money like a latch. You have sentences like:
when vend => money <= money - "1001011"; etc. This is not a recommend style of coding for synthesis n a FPGA. A solution may be: process(rst, clk) begin if(rst = '0' ) then money_reg <= ( others => '0' ); elsif(clk'event and clk = '1' ) then money_reg <= money_next; end if; end process; process(Money_reg, ....) begin money_next <= money_reg; case ... is when .... => money_next <= money_reg - "1001011"; ... end case; end process; You create a register for vector Money.
