HDL Help.

Can anyone suggest me a place to start learing HDL.

All internet searches have left me very confused on what the HDL software is.

All I know is that it is a simulation lnaguage for the Hardware.

Thanks,

HDL is Hardware Description Language.
It was originally designed just as a simulation tool. However, it soon became used for synthesis as well. That is, you can write a design in terms of a complicated logic equation for example and there are tools which can turn it into a version made of AND/OR gates, and then all the way down to individual transistors including the silicon dimensions.

Where do I get the synthesis and simulation tools? open source software/demos/Sharewares?

And is there a good tutorial anywhere to start learning? I could not find any good leads from google. Maybe I used the wrong keywords...

Thank you.

This is a good place to goto, got quite a few bits from here.

I do have a good simulator, but it is installed in my Linux partition and I am in windows atm, when I next boot into linux ill find the program name.

VHDL doesn't just have to simulate hardware.

At work we have a FPGA:VHDL motor-controller and to "test-bench" it we have a brushlessDC machine written in VHDL as well as the analogue current-loop, bloody good as well

Look for Webpack.

Webpack offers a free synthesizer (XST), Simulator (Model SIM - limited)
And code entry & organization. Good stuff. Get on it.
