请问这段代码哪里写错了 刚学VHDL 错误在with temp1 SELect这一行
if buttons(0) = '1' then
digit<="1110";
segments(7)<='1';
with temp1 SELect
segments<= "1111001" when "0001", --1
"0100100" when "0010", --2
"0110000" when "0011", --3
"0011001" when "0100", --4
"0010010" when "0101", --5
"0000010" when "0110", --6
"1111000" when "0111", --7
"0000000" when "1000", --8
"0010000" when "1001", --9
"0001000" when "1010", --A
"0000011" when "1011", --b
"1000110" when "1100", --C
"0100001" when "1101", --d
"0000110" when "1110", --E
"0001110" when "1111", --F
"1000000" when others; --0
if buttons(0) = '1' then
digit<="1110";
segments(7)<='1';
with temp1 SELect
