Sharing VHDL Verification IP

Sharing VHDL Verification Components (VVC) within the FPGA/VHDL community has previously been difficult because there was no standardised way of interfacing to and controlling these VVCs. A solution on this challenge could easily reduce the project verification time by 20 to 80%, and at the same time improve the FPGA quality. The open source UVVM has over the last two years standard

Seem to get better results when using inferred data paths? E.g. letting the synthesis tools insert the multiplexers where they see fit gives better Fmax than laying out the datapath in complete detail. Also don't need to remember and code all the control signals for the muxes. Still code intermediate adders and such to keep the number of inferred carry chains down. Comments? Jim Brakefi...


Xilinx Custom IP accessing 16-bit bram

Hello, I have used Xilinx core generator to synthesize a bram with width of 16 bit and depth of 80k, resulting a 17-bit address. Let's call them bram_data, and bram_addr. I am connecting the bram to PLB bus which has 32-bit address (Bus2IP_Addr) and 32-bit data (Bus2IP_Data). I am not sure how to connect those two together since I don't understand that if the address is not at the...

I finally got a test case for my FPGA async one-shot idea, hacked into a build for something else. I got 17 different one-shots, with various pin locations and speed/drive strength settings. https://www.dropbox.com/s/4hxena27mpbpg54/FPGA_OS_1.JPG?raw=1 Most of the outputs look like this, with remarkably consistent timing, edges within a few hundred ps. This is typical: https://ww...

I'm trying to decide on which to use for a project as the main default that may include a number of freelance people. can you say which of these you actually use (the most) and have the best skills in Verilog systemVerilog SystemC VHDL Other And if possible what type of work you use it for in general I dont need to know why you use a particular one - and to avoid flame wars ...

What are thoughts on these two vendors goods? I like that they have cheap(er) PCIe options. My intended use case is to learn about HW and HDL development with an existing strong OS development background so I want to write device drivers to interface etc. Right now I'm leaning toward Lattice but I like that Microsemi is embracing RISC-V.
