我安装的是Quartus II 11.0,编译程序的时候出现了Error:current module quartus_asm ended unexpectedly 以及Error:current module quartus_sta ended unexpectedly 的错误提示，求大神分析原因，程序如下：module detect_module
(
CLK, RSTn, Pin_In, H2L_Sig, L2H_Sig
);
input CLK;
input RSTn;
input Pin_In;
output H2L_Sig;
output L2H_Sig;
/**********************************/
parameter T100US = 11'd4_999;//DB4CE15开发板使用的晶振为50MHz，50M*0.0001-1=4_999
/**********************************/

reg isEn;

if( !RSTn )
begin
Count1 <= 11'd0;
isEn <= 1'b0;
end
else if( Count1 == T100US )
isEn <= 1'b1;
else
Count1 <= Count1 + 1'b1;
/********************************************/

H2L_F1 <= 1'b1;
H2L_F2 <= 1'b1;
L2H_F1 <= 1'b0;
L2H_F2 <= 1'b0;
end
else
begin
H2L_F1 <= Pin_In;
H2L_F2 <= H2L_F1;
L2H_F1 <= Pin_In;
L2H_F2 <= L2H_F1;
end
assign H2L_Sig = isEn ? ( H2L_F2 & !H2L_F1 ) : 1'b0;
assign L2H_Sig = isEn ? ( !L2H_F2 & L2H_F1 ) : 1'b0;
endmodule |
