Spice agent is the equivalent of vmware/virtualbox "guest additions," and is the thing you want to install on your guest if you're using virt-manager on Linux. It lets you do things like dynamic resizing, copy/paste

I'm pretty sure Bluespec and SpinalHDL compile to Verilog. Chisel uses it's own IR (FIRRTL). I think Migen used to target Verilog, but now targets (one of?) the IR(s) that Yosys supports (RTLIL?).

I think/hope it's an unstable equilibrium -- if either Altera/Intel or Xilinx/AMD give a nod to the open source tools, the others will follow. Lattice is seemingly at "wink wink, nudge nudge" levels of support

For decades, the FPGA vendors have had this fever dream of "an FPGA in every PC" -- either as an add-on card, or as part of the chipset on a motherboard -- that would enable a compiler or operating system to seamlessly accelerate

The best ARM SoC you can currently buy on the open market (without a backroom deal) is a combo A72/A53, which is what Pine64 sells. If you want to change this, you'd need to either start a semiconductor company, or engineer some s

Sorry, I misunderstood your original comment. When you said: > Up, flat, down, flat. Guess what: you've just introduced enormous amounts of aliasing. I thought you were suggesting that the jagged, stair-step output of a DAC is wha

You miss a lot of nuance when you're busy being blunt. An ideal signal that you want to approximate may contain infinite frequency components, but this property alone is not what gives you aliasing artifacts. Sampling incorrectly does.

You and I are in agreement. An ideal square wave is not a signal that is band-limited to the audio range, so attempting to sample it directly (the naive approach) doesn't work. Instead, you want to sample a band-limited approximation

This paper was thoroughly entertaining. Thanks!

Disks and pads wear out. I haven't done the math, but I assume you could put in a big (wine bottle sized?) power resistor that can take the thermal cycling more or less indefinitely. You'd have to cool it, as other commenters have

I guess that's easier and cheaper than adding a circuit to keep regenerative braking on, but dump the energy into a big resistor...

It's clearly a typo. Should be "This works for wavelengths larger than the cavity size." A long wavelength implies that the phase of the reference input and feedback input are similar, which is what allows you to just subtr
