verilog array assign
As @toolic has mentioned for loops are synthesizable. This is the case were it is perfectly fine as it can be statically unrolled. The inner loop may not be necessary but I find some version of synthesis tools struggled with memory (array) assignments, t, If the values (coefficients) is saved in an external file (for example 'file.txt'), you can use system functions in simulation ( $fscanf ) to read the values from the file and wirte them on the datafile ( datafile is an array). In the following c, For that logic you'd probably like to use for generate loop: generate for (i=0; i<8; i=i+1) begin : led_loop assign LED[i] = (some logic); end endgenerate., First of all, you can't assign to regs. assigns drive wire types, not reg types. To drive a reg type you need a statement inside a logic block like an always block. Secondly, based on what you've written, I think you're looking for an array o, To assign an unpacked arrays braces with tick ' and } are used, provided all the values of the array should be assigned. usage example module top ( input i); wire d [0:1][0:3]; wire a [0:1][0:3]=' '1,1,1,1}, '1,1,1,1} }; wire b [0:1][0:3], If I understand you correctly, you're looking for a simple assign construct: assign tag_in = tag_in_reg;.,mem[4][15:0] = 16'h0002000000000000; and $strobe("%b", icon); need to be in an assign statement, initial block, or always block. mem is also delcared incorrectly if you want to assign as mem[4][15:0] . it should be declared as double packed,, Only SystemVerilog allows you to assign arrays as an aggregate. Change the file extension from *.v to *.sv. Another option is to use $readmemb and load the lookup table from another file., "Regarding blocking and non blocking assignments - basically i need assigments in always @ block to happen in order: first, i load value from input, then i need to get appropriate array element using this value as an array index, then i need to driv, Assigning and Copying Verilog Arrays. Verilog arrays can only be referenced one element at a time. Therefore, an array has to be copied a single element at a time. Array initialization has to happen a single element at a time.
