Re: [neonixie-l] Who simulates or protoypes their designs before doing a PCB ?

[gregebert]

I tried LTSpice 10-12 years ago because it has models of many of the IC's 
from Linear Tech; a lot of other IC manufacturers dont supply models at 
all, or only with an NDA. It's a great tool, but I generally dont use it 
because it's PC-based, rather than Linux, which I use for my other design 
work. I may give it another try if I mount a Linux disk onto the PC (so far 
I have not, largely out of security concerns; my PC is more likely to get 
hacked than my Linux machines, and having a pathway between them makes 
things less-secure).

The other reason I used LTSpice was that I could run sims during work 
breaks; my employer's firewall blocked remote access to my home network. 
But, that problem has been solved because I'm now retired.

Netlisting out of your schematic-capture tool, rather than from LTSpice, 
and into your simulator (SPICE, Verilog, etc) is a good way to catch 
design-entry errors that can sneak into your PCB layout otherwise 
undetected.

 Since I'm a longtime designer of IC's, I rely heavily on simulations: 
 ngspice for the analog sections, verilog for the entire PCB (logic, FPGA 
 if 
 any, and analog). Once that is done, I go straight to PCBs with no 
 prototyping. So far, I've only had 1 project that required any 'blue

 to fix a design error.

Maybe the problem was the typo I had in Singer-Friden... 
I wrote Friden with an extra e, that means peace in german...
Makes no sense to me, but it's google :-)

Re: [neonixie-l] Who simulates or protoypes their designs before doing a PCB ?

['Grahame Marsh' via neonixie-l]

I am a chemical engineer and when I retired I was working on the safe 
landfall of north sea oil and gas. I have little formal electronics 
training and I'm mostly self taught That said


 I do a mixed bag of experiments using dead insect on a copper sided 
PCB, a plug in board, a literal breadboard (mostly for valves), strip 
board when I want something semi-permanent or for a long running 
experiment and simulations using LTSpice. I tend to do what I think is 
best at the time for the tests I want to perform. I do enjoy building 
things, this is the hobby after all.


My use of LTSpice is limited to analogue stuff and some power supply 
simulations. I've not had too much success with designs that use 
inductors in particular. But I spent some time simulating various CRT 
deflection amplifier designs before moving to a PCB and I was not 
disappointed by the results. I know I should simulate more before 
heating up the soldering iron...


For PCB design I own an unlimited copy of Eagle 7.7.0 which was the last 
version before they went subscription based. It is getting old now (like 
me) and I have looked at some of the all-in-one design software but 
Eagle does what I want (schematic to Gerbers), I know how to use it and 
I have a large component library that I have developed myself. So I 
don't feel a need to go anywhere else: I am unconvinced that the 
facilities in any new software would be repaid the time I would spend 
learning how to use it. But my prototype PCB designs often have 
problems: they tend not to be "electrical" but "mechanical" in nature. 
Components are too close or I goof with the silkscreen such as I label 
things incorrectly - this is just incompetence I know.


Going back to the simulation question - I started with QUCS and then 
moved to LTSpice - should I look to use another simulator? What should I 
look at beyond LTSpice?


 Keep in mind my limited knowledge of electronics and the need to 
self-teach!

I sometimes use LTSpuce for analogie simulations where many different 
positive and negative voltages are present as my skills ate inferior when 
it comes to electronics, I especially did this when figuring out how to 
design coupling stages and driving stages for the A-201 Polyatron some
