If instead of a pulse you change the sign of the output, it will generate a rectangular signal with a duty cycle as close as 50% as you can get, with a frequency of Fsys * a / (2*b) Be careful if you plan to use this generated signal as a clock inside the FPGA i...
Hello! In my Verilog design I have a 25Mhz board clock from which I derive a 100Mhz clock. Coming from an external Pin I have an asynchronous 4.77

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 ...
though; they won't affect "synthesis" per se (as far as I know anyway - the synthesis tool itself has no means of checking, even less so trying to enforce, this kind of constraints), but will affect place-and-route (PAR), as Bassman59 said, and possibly map as well in some cases...
As @bruce_karaffacek4 mentioned the clocking wizard IP is used for Frequency Synthesis, Now Suppose that you need a 300 Mhz clock in your design, but the board only has a 200 Mhz input at U6, So you can use the clocking wizard IP to multiply, divide the 200Mhz clock and...
Step 15:Create the HDL wrapper for the BD and run synthesis and implementation, then generate the device image. Step 16:Export the hardware design to get the XSA file. Step 17:Create a new application project in Vitis and switch to the "create a new platform from hardware tab". Click on...
If you are interested in learning more about testbench design using eitherVHDLorSystemVerilog, then there are several excellent courses paid course available on sites such asudemy. Architecture of a Basic VHDL Testbench Testbenches consist of non-synthesizable VHDL code which generate inputs to the...
Cell library characterization is a process of analyzing a circuit using static and dynamic methods to generate models suitable for chip implementation flows.
