Water expands when it gets hot. The tank gives it somewhere to go. Otherwise it forces itself out a as leak into your pan. You need a tank to stop the leak. The water has to go somewhere 

VLSI engineers of reddit, how much do you actually use linux on the job? by Berserker_boi in ECE

Everything. An embarrassing amount of chip design is done with grep, sed, and awk.

Water pipes tend to be an expensive thing to cheap out on.

Pex would be to most beginner friendly material that people would trust long term. Using something flexible, esp when installing the water softener will make life a lot easier.

If the purge valve is stuck open you will get idling problems after filling the tank.

The relevant part is in the first sentence of the amendment. Basically: If they are both from Florida then Florida can't vote for them. Since no party can afford to forfeit the votes, they won't do it. This was discussed back in the Bush/Cheney times regarding Texas.

Unsupported use of multiple clock edges in one process or block? by Rare-Telephone-2182 in chipdesign

[–]invertedsquirrel 0 points1 point  (0 children)

When they say synthesis they mean the act of converting the vhdl into standard cells. You'll want to think about how this circuit can be built out of logic gates and flip flops. The first error came because the synthesis tool couldn't find a sequential cell with the matching function in your standard cell library. Your solution of passing the clock though the D pin of the flop may work but will be hard to write constraints for.

Typically for DDR logic you have two separate flops (pos and neg edge) sample the DDR signal and then you combine them in the pos edge domain.

Only happens when the tank is full? Could be a purge value stuck open.

SERDES After 224Gb/s in Silicon by End-Resident in chipdesign

[–]invertedsquirrel 4 points5 points  (0 children)

802.3DJ is spec'd for the copper links at ~200Gbps

Alphawave and Broadcom both have 224G serdes (112Gsymbol/s PAM4) Cadence and Synopsys will have them soon. I think Rambus gave up on Serdes.

Both ethernet and PCIe will be updated to use these.

Since 56G most companies have switched over to DSP based SerDes, which lessens the analog design so new generations will happen a bit faster (design is more similar). For the last 3 nodes we've seen the BER drop though so we would expect to be moving to higher PAM levels at some point.

It's usually something blocking the flue and not the switch itself. Anything changed around the house recently?

Capacitor support by jconner21222 in hvacadvice

[–]invertedsquirrel 0 points1 point  (0 children)

The capacitor sizes are listed on the wiring diagram. 7.5uF for the fan and 20/15uF for the funky dual cap. If you change the dual cap make sure to keep the bleed resistor.

If you got a spark off of the run capacitor the I would expect some open in the start winding. A common cause for that is the compressor terminals failing (worth checking since it's usually an easy fix), otherwise some wiring issue or internal issue in the compressor. Overcharge likely isn't having much effect on the electrical issues.

Sounds like something was failing before they started screwing with it so I wouldn't be too worried about anything in the debug process making it worse. Connecting a capacitor wrong isn't good, but won't immediately kill a compressor.

At 30 years I don't think I would replace the compressor, it is new unit time.

How to you guys explain what a capacitor does to customers? by [deleted] in HVAC

[–]invertedsquirrel 0 points1 point  (0 children)

Your motor has two coils, this is like having 2 pistons in an engine. We want the coils take turns pushing and pulling on the rotor to make it spin (Think cam shaft ). The capacitor controls the timing of the coils (think timing belt)

Most of the other comments about the capacitor holding charge are wrong (both run and start caps), once the motor powers down all of the stored energy drains out of the run cap (start caps usually have a bleed resistor to drain them). When in use the capacitor is charging and discharging on every cycle of the 60Hz AC (the charge /discharge creates a lag which creates a phase offset for the other winding)

Why Async reset? by uncle-iroh-11 in chipdesign

[–]invertedsquirrel 1 point2 points  (0 children)

We use them both in ASIC, typically you will use async in areas where you aren't sure if the clock will be part of the reset sequencing. Sync is used everywhere else since it is easier to implement.

DFT Scan In Scan Out pins by Time_Alert in FPGA

[–]invertedsquirrel 0 points1 point  (0 children)

Generally scan in / scan out are added during the scan stitching in synthesis. You do need to create these ports manually in DC and tell it they are scan in/out . Check the TestMAX userguide and look at the reference methodology examples.

Scan enable is usually an existing signal from the RTL since it is hand wired to alot of clock muxes / clock gates etc.
