I think the right way isn't "learn a HDL", it's "learn digital electronics design". Hardware description languages enable succint hardware description, but it's still necessary to keep an image of the actual hardware in mind.

HDL is really just ascii schematics.

I often find it easier to grok things like circuits and logic visually, certainly when in circuit design/PCB mode.

Does anyone know of any open source software for taking smallish chunks of Verilog/VHDL and making a visual representation/schematic?

I wrote a small blog post about using netlistsvg, yosys, and ghdl to make block diagrams for VHDL here: https://nobodywasishere.github.io/netlistsvg/

Thanks. Very useful.

yosys with yosys show command can do it for Verilog: http://www.clifford.at/yosys/files/yosys_appnote_011_design_... I found it really helpful to see what a chunk of Verilog code would look like after synthesis.

There is an online version at here: http://www.clifford.at/yosys/nogit/YosysJS/snapshot/demo02.h... which uses YosysJS. Hopefully someone can port Compiler Explorer UI to this

I had a feeling yosys might do it somehow. Thanks.
