The frequency step can be in KHz (course) if necessary for trade off with better jitter and synchronous clock. I have also tried to use the Mega Wizard to PLL to output 1 clock at 500 MHz and the 2nd output at 200 MHz but these two don't sync up. Any help will be ap...
In this article, we will learn how we can use Verilog to implement a testbench to check for errors or inefficiencies. We’ll first understand all the code elements necessary to implement atestbench in Verilog. Then we will implement these elements in a stepwise fashion to truly understand the...

Title: How modeling static RAM in Verilog Post by: caius on October 31, 2024, 10:11:49 pm Hi all,it came the time for me to model a static RAM in Verilog.I'm uncertain if using registers or block, the RAM must be static therefore asynchronous.I attach the schematics (one RAM ...
You can check in the respective device handbooks. Also your Verilog code is specifying this operation. So the design compiler should either implement or reject it, but not add a delay cycle. Did you perform a functional or timing simulation? What's the involved device, ...
To resolve a defect in BootROM requires a new revision of the chip, if found during silicon validation, hence it is very important that we do 100% testing of the code before base layer tape-out of the SoC. By testing BootROM in Simulation and Emulation environments simultaneously, thorough...
A general-purpose color-space-conversion instruction for Tensilica's synthesizable Xtensa processor, for example, adds 7,500 gates to the base processor design, resulting in an instruction that converts one pixel into YCrCb at the rate of one conversion in two clock cycles. The net accelerati...
Looking back at our example from last post where distributed RAM was used to implement our design, we can seeRAM32MandRAM32X1Delements. Schematic view of themaybe_bramVerilog module. TheRAM32Melement is described as follows in the Xilinx docs: ...
The following sections contain step-by-step instructions how to implement the most common use cases, plus low-level functional schematics of CLB building blocks to aid the process of mapping logic from VHDL or Verilog into CLB. Many powerful and flexible CLB features provide you with substantial ...
