i have an error Fatal Error: Access Violation at 0X000001873EF24868
I created an element in verilog code:
module lab2_2_v
(
input [0:3] x_n,
output y1
);
wire x1 =~ x_n[0];
wire x2 =~ x_n[1];
wire x3 =~ x_n[2];
wire x4 =~ x_n[3];
assign y1 = ( x1 & x2 & x3 & ( !x4 ) ) | ( x1 & ( !x2 ) & x4 ) | ( ( !x1 ) & ( !x2 ) & x3 ) | ( ( !x1 ) & x3 & x4 );
endmodule
In modelsim I tried to count value "count every" - quartus crushed
