    1 and above Help indicates some possible causes of this syntax error. This error can also occur in the Quartus II. I am trying to code a memory test algorithm in Verilog. This code is a part of it. I am trying to write a state machine to set the read select signal. I am getting compilation errors like : near " endcase" : syntax error, unexpected. In this lines: coutminus1 = c[ 0] ; cout = c[ 1] ;. the keyword assign is missing. There are also some other issues with your code. I' d propose to change it to something like this: module trojan ( input [ 1: 0] a, b, input ci, sel, output [ 1: 0].

The standard, which combined both the Verilog language syntax and the PLI in a single volume, was passed in May 1995 and now known as IEEE Std. Verilog syntax and structure. In Verilog, a design entity has only one design unit, the module declaration as depicted below. Two main issues, assignents can be made using assign to wires or delcare as reg and place in an initial or always block. For example: module segment7dec ( input [ 5: 0] bin, output reg [ 3: 0] bcd0, / / < - - reg type output reg [ 3: 0].
