How many PCB prototypes does your company allow in hardware design?
Some prototype PCB's are expensive. I worked PCBs worth 1000 dollars (10 layers of blind via and impedance equalization, etc.).
What is expected from me is that the PCB works in the first design, if there is any mistake I get a ton of mobbing. How is it at the company you work for?When I want a second prototype, and I get suggestions like "it should work on the first design". Is this normal?
Especially when designing analog circuits, spice models can include simulation times of 7-8 hours (Cascade circuits).
Divide and conquer spice simulations are partially faster. However, it can be difficult to predict what will happen in "cascade circuits". The simulation provides results to some extent.
For example, in the data sheet of an opamp, everything such as chopper noise results etc. can be included and noise analysis can be done. However, sometimes there may be unexpected noise. (Meanwhile, I am reading technical books and making designs to broaden my perspective and learn more topology sub-topics.)
Analog digital circuit topology design , power design, analog and power spice simulations , PCB place and route, high speed ddr electromagnetic simulations, power integrity ,syz parameters, signal integrity, decoupling cap optimiazation, impedance analyses), all of them I analyze it myself.But there are still points I miss.
I also have to test pcb , time domain oscilloscope, vna for pdn impedance etc and SA analysis for active filter characteristics.
What about your experience?
