Sometimes an error is on one line of code, but the error isn't reported until another line, so you may have to look up one or more lines in the code. Source(s): Programmer/Analyst.

I just copied your text into the file dff.v and ran: vlog dff.v vsim dff and it didn't throw any warnings or errors. Now on the other hand you should use non-blocking assignments in your clocked always block as this represents HW. If you don't know the difference read the following: http://www.sutherland-hdl.com/papers...ng_assigns.pdf Also you should use the C like syntax for the port definitions, so you don't have to keep repeating the port names. module dff ( output reg q, q1, input d, d1, clk, reset ); etc..

There is no one else to ask this and am following the same outline of the example in my reference book. What am I doing wrong? module Main_Module(a, b, c, d, e, f, g, U, R, P, Clk); input U, R, P, Clk; output a, b, c, d, e, f, g; reg [3:0] Data; wire In3 <= Data[3], In2 <= Data[2], In1 <= Data[1], In0 <= Data[0]; //This is Line 25 Counter Counter_1(Clk_1Hz, R, P, U, Data); Segment_Display Segment_Display_1(a, b, c, d, e, f, g, In3, In2, In1, In0); ClkDiv1Hz ClkDiv1Hz_1(Clk, R, Clk_1Hz); endmodule Thank you Eugene Sh.and Greg for your time! verilog share|improve this question edited Dec 17 '14 at 23:36 Majenko 44.6k263127 asked Dec 17 '14 at 20:32 user3465945 33 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted Wires need blocking assignments (=), not non-blocking (<=). You can define it this way: wire In3 = Data[3], In2 = Data[2], In1 = Data[1], In0 = Data[0]; Example here More commonly you will see the declaration and assignments as separate statements. The two are functionally equivalent wire In3, In2, In1, In0; assign {In3, In2, In1, In0} = Data; share|improve this answer answered Dec 17 '14 at 21:14 Greg 2,574820 That Works! I always had this problem with assignments, though could get away with "<=" in all assignments I need. Do you know if t
