The basis of good design is good tools and good parameters.
We have some wafers with the PCM (process control module) between the dice. I want to extract parameters from those, for checks.
What is the best way to generate simple but efficient models ?
What is the good software ? UtMos?
What are the good measurements ? with what kind of tools ?

kevpat is right. They are not the same (not even close). The unijunction transistor is a switching device. Its primary parameter is the "intrinsic standoff ratio" (eta). The device has two bases and an emitter. When the emitter voltage exceeds a value equal to the inter-base voltage times eta, the devices switches and the inter-bas

I can see some of your transistors, but you need first to place them then use SHIFT+F.
Sometimes Layout XL looks like lagging in such issues.
Try shut down icfb and restart. Tell me the results.

Is there any tool which can draw my transistor level layout, by a verilog netlist?
I have used tools like Microwind but this tool isn't complete and there is no way to limit size of layout and it isn't very clever in drawing automatic layout so it will providing a big layout which is not acceptable in area size!!

Yes, that's true. You would use a circuit, that can tolerate some amount of hFE variation by utilizing feedback. Most practical transistor circuits have it.

Cadence's Conformal-GXL (or Conformal-Custom) can take read transistor spice level netlist and convert that to a verilog structure. The verilog structure can in turn be verified against RTL. You will however, need the Conformal-LEC-Custom license if you want to run the RTL to transistor level checks.
Revised: spice -> Verilog

It is basically a device, like a bipolar transistor, set up to oscillate. But there is a RC bias circuit (with an audio frequency time constant) that quenches the oscillations just at the point that it is ready to take off. Since an oscillator has "ionfinite gain", this almost oscillator has almost infinite gain. Not a bad trick for one device.
