Background of Wave window in Questasim Does anyone know how to change the colour of the background of the Questasim Wave Editor? SolvedRe: Syntax error in initial block Thanks a lot. That is indeed the problem. I have no idea how that back tick crept in as I do not have it on my keyboard. Perhaps I copied it from somewhere though I cannot remember. Re: Syntax error in initial block The error messages for each line within the initial block are: Error (10170): Verilog HDL syntax error at dsb.v(10) near text: . Check for and fix any syntax errors that appear immediately before or at the specified keyword. Error (10170): Verilog HDL syntax error at dsb.v(10) near text: " "; expecting ";". Check for and fix any syntax errors that appear immediately before or at the specified keyword. Code before the initial block is: module dsb (clk_c, plc_lsb, plc_usb, dsb); input clk_c; output plc_lsb, plc_usb, dsb; reg [3:0] div, lpc, pa; // div = counter used to obtain clk_m from clk_c wire [3:0]sub, add; reg [7:0] plc_lsb, plc_usb; reg [8:0] dsb; initial begin div = 4’b0; lpc = 4’b0; pa = 4’b0; plc_lsb = 8’b0; plc_usb = 8’b0; dsb = 9’b0; end Syntax error in initial block I am using Quartus Prime Lite Edition v22.1.1 In my Verilog HDL code, I include the following initial block: initial begin div = 4’b0; lpc = 4’b0; pa = 4’b0; plc_lsb = 8’b0; plc_usb = 8’b0; dsb = 9’b0; end A syntax error in every line of the initial block is generated when I compile the code. I do not see anything wrong with the code though. SolvedRe: USB Blaster cannot be selected To my embarrassment, I accidentally found out that the driver is installed when the PC is rebooted with the development board switched on and connected to a USB port. Anyway, perhaps someone may find this simple solution useful. Re: USB Blaster cannot be selected I am using Windows 11. Re: USB Blaster cannot be selected Apologies, I was too hasty in my reply. In 'Control Panel' -> 'Printers and Devices' -> 'Bluetooth and Devices', under 'USB Blaster', it is mentioned that the 'Driver is unavailable' Does anyone know where to download the driver? Re: USB Blaster cannot be selected Thanks for your reply. The driver has been correctly installed. Hence, that is not the solution I am afraid. Re: Error in Timing Simulation Display Thank you very much for this information. I will definitely look into it.
