Using GHDL for interactive simulation under Linux
The opensource and free VHDL simulator 'GHDL' has been out for many years, but like many other opensource tools, it has caught limited attention from the industry. I can hear you thinking: 'If it doesn't cost money, it can't be worth it'. Well, I hope this short overview will change your mind and even whet your appetite for more. Because, using some extensions, you can do some quite funky stuff with it that will save you a lot of debugging work. For example, simulate your real world software...
Developing FPGA-DSP IP with Python
This blog post was previously titled MyHDL ASIC Proven (How is this related to FPGAs?) but the blog post has been updated and mainly discusses developing FPGA-DSP IP with Python / MyHDL. The original content is still present but the post has been reorganized and expanded. Original post 16-Mar-2010.
Developing FPGA-DSP IP with Python / MyHDLUsing Python to develop DSP logic for an FPGA is very powerful. The Python ecosystem contains many packages including numerical and...
MyHDL @EDAPlayground
Trying out MyHDL became a little easier recently. MyHDL is now avaialbe @EDAPlayground. One can experiment with Python/MyHDL verification of HDL modules and implementing complex digital cirucits in MyHDL.
The @EDAPlayground has two main panels. On the left is the testbench and the right the HDL description to be tested.
There are a couple examples...
[Comments] C HLS Benefits
Earlier this week I posted a small write-up comparing a hardware median calculation implemented in a C-to gates "HLS" (Vivado C HLS) and a version in MyHDL. For a long time I have had the belief that C-to-gate technologies are of little to no benefit - based on the simple premise that "C" is not that high-level of a language (I actually consider it lower than Verilog and VHDL ... but that is a conversation for another time).
Language comparisons...
MyHDL Presentation Examples
The last two years I presented at EELive. The first year as an overview of MyHDL and a strong case why you should be using MyHDL as your hardware description language (HDL) [paper]. The second year was an introduction to three alternative HDLs (alt.hdl), including MyHDL. I also presented at a regional Python conferene: pyohio. At the Python conference I presented...
