Re: How to add time delay in verilog code « Reply #2 on: June 06, 2016, 11:07:00 pm » You must always keep in mind that you're describing hardware, not writing a program. So you need to think how you would implement a delay in hardware - make a counter (or maybe a sh...
if you want to delay a signal in real life, use LCELL. and delay time of LCELL will vary by temperature of processor itself. each LCELL may give you approximately 0.5ns delay. so if you need 5ns for example, you would actually need to pass signal through ...

The DVI-to-RGB IP has no way to invert signals and I think there is no way to do it but to make changes in the IP code. I'm a Verilog guy at best.. and it is written in VHDL. I see a file called InputSERDES.vhd which seems to contain the IBUFDS: ...
I’m not sure I’m young enough to think that hard anymore. However, here’s a few more thoughts before I go ice my head. We don’t usually use CLKFBOUT for a clock output – mostly, I suppose, because the Clocking Wizard does not give us this option. However, the waveforms in ...

some DFFs, and multiplexers are required to implement the FPGA-to-LCD interface. Additionally, we need an FSM to control these building blocks. The next article will give the details of designing the FSM and writing its Verilog code. Then, we’ll program the Mojo V3 board to...
delay. Our deadlines were set in stone and we wanted to choose the best ASIC design house that we could afford. Some team members wanted to work with a local ASIC company to save travel time and avoid communication problems. Other members preferred seeking an off-shore team that had proven...
VHDL code likes to see a component definition to tell it what the connectivity is. So if I have a Verilog module called 'example' with a clock and reset input, and a d input and q output, then in the VHDL file in the architecture section you need: architecture ... -- Verilo...
To get a 20 MHz output with roughly symmetrical duty cycle, you need 25 ns delay, I guess about 50 to 100 logic cells of MAX II. In HDL, you need a keep synthesis attribute to prevent elimination of the redundant logic cells during synthesis. Don't know how it wor...
