Infrastructure - running 32-bit applications on a CentOS 64-bit machine (Modelsim IntelFPGA)

ModelSim - Intel FPGA Edition is a powerful simulation tool designed for FPGA design verification. It offers comprehensive simulation capabilities, supporting both Linux and Windows platforms. The Starter Edition is available for free installation without a license, making it accessible for a wide range of users.

If you are on a CentOS (7/8) 64-bit machine, chances are that you get weird errors while running vlib/vlog/vcom/vsim commands after installation. Below is how our team recently fixed it for a local FPGA house. 

Below are the steps to get all necessary packages installed. Given the nature of Linux in general - your mileage may vary, we would love to hear in comments below if you find this useful, any more errors that you encountered during this installation etc. 

ModelSim - Intel FPGA Edition may not run on CentOS 7 because it is a 32-bit application, and CentOS 7 is a 64-bit operating system. Here are some potential solutions:

Install 32-bit Libraries: Ensure that the necessary 32-bit compatibility libraries are installed on CentOS 7.

sudo yum -y update --skip-broken
sudo yum -y install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32ncurses6 libxft2 libxft2:i386 libxext6 libxext6:i386
sudo yum install libstdc++.i686
sudo yum groupinstall "Compatibility Libraries"
sudo yum install libXft-devel.i686

Don't go "wild" with Associative arrays in SystemVerilog - PySlint it!

Image
 Hash tables, modeled via Associative arrays is a powerful data structure in SystemVerilog. Python calls it as "dictionary". One of the "wild" features of SystemVerilog is that it allows associative arrays to be declared with arbitrary key type. An example:           class wild_c;             string wild_hash_table [*];           endclass : wild_c While the above is a legal SystemVerilog code, may even be seen as "easier" to write, it is bad from a reuse perspective. Some of the side effects (mostly bad) are: Unclear data structure to begin with - for writer and then the reader/maintainer of the code.  As the key can be anything, SV does not allow wildcard indexed associative array to be iterated via foreach loop. It cannot be passed as function parameter. Many find*  methods do not work on wild-card indexed associative arrays. For instance, find_first would need to return a queue of the keys, and when used on wild-card indexed array, it would be a queue o

Porting a complete UVC to Verilator + UVM - an anecdote!

Image
 So, here we are on Day-1 of UVM + Verilator becoming available to the public, start of democratizing chip design verification. In case you just woke-up/started on this topic, read the release of UVM + Verilator with some intricate details on the challenge on the way by Antmicro via:  https://antmicro.com/blog/2023/10/running-simple-uvm-testbenches-in-verilator/  Awesome work by the folks at Antmicro and fantastic support by the ecosystem specifically Western Digital, kudos!  At AsFigo , we are committed to fueling open-source driven chip design and verification. So we took this opportunity to port a commercial-grade UVC (Universal Verification Component or a Verification IP) and ported it to compile and run on Verilator. Below are our reflections from this experiment. Get in touch with us to discuss how AsFigo can help your VIPs and testbenches to be ported to opensource EDA.  Case study: VLBus - a simple peripheral bus intended for write/read to configuration registers (like the pop

Opensource testbench generator for VHDL designs, OSVVM included!

Image
VHDL holds a prominent position in the world of FPGA design, particularly within the military, aerospace, and defense sectors. It serves both as a Register Transfer Level (RTL) design language and as a tool for creating testbenches. The availability of open-source simulators, such as GHDL and NVC, alongside numerous free FPGA simulators and synthesis tools, has provided FPGA designers with a significant advantage over their SystemVerilog counterparts. While the Universal Verification Methodology (UVM) is widely adopted among SystemVerilog users, VHDL practitioners have traditionally relied on various homegrown methodologies and frameworks. Recently, however, off-the-shelf methodologies and frameworks such as OSVVM, UVVM, and VUnit have become available to VHDL users. Each of these options presents different levels of complexity, allowing users to choose the one that best meets their needs. Despite these advancements, the development of open-source utility tools supporting the latest me
