An example task

An excerpt from a real sample datasheet. The model gets text like this and nothing else: no schematic, no circuit, no hints.

Sample part 9 V supply · 2 inputs · 3 outputs · 2 test points

With in1 held low, in2 falls from 8.5 V. out3 falls from about 8.6 V to 0.07 V.

Parameter	Temp.	Min	Typ	Max	Unit
Delay, in2 edge to out3 = 1.80 V	−40 °C		22.92		µs
	25 °C	16.74	18.51	20.89	µs
	85 °C		14.49		µs

out3 after the in2 edge. The crossing times are the datasheet's; the curve shapes are drawn for illustration.

Allowed parts: 2N3904, 2N3906, 2N7000, BS250P, 1N4148, 1N5231B, E96 and E12 resistors and capacitors
Budget: At most 68 parts

What the model has to do

Choose a circuit architecture. Nothing in the datasheet says what it should be.
Pick parts and values from the allowed list, within the budget.
Simulate and revise until every line of the datasheet holds at −40, 25 and 85 °C.

The grader then checks this delay and every other line of the full datasheet. The full datasheet is much longer than this excerpt.
