Well.. looking at it this way.. FPGA desiners use a lot of non-graphical
EDA design data with VHDL and verilog. That doesn't seem to stop them,
so I don't see why it shouldn't transfer for some aspects of electronics
design too. I'd have thought it applied more easily for digital, than
discrete analogue stuff though.

(I personally prefer a hybrid approach with FPGA design.. schematics for
high-level blocks showing the architecture, then VHDL for the innards.


Best wishes,
