This sounds like a good low-level API. But from a convenient python
wrapper I would expect a bit higher level of abstraction.

How about building class hierarchy? Let me know what do you thing
about following sketch.

from Gnucap import Tran, NetGnucap, Wave, AsciiTabular, Measure
(exception should be thrown if some commands are not available)

net = NetGnucap.get("aCircuitFile")
net.xsubckt1.setBlockName("block2")
net.xsubckt1.MMload.setParam("w", 10e-6)

out = Wave(step=1e-6)
out.save(net.xsubckt1.net1, net.xsubckt1.net2)
out.setFormat(AsciiTabular())

sim = Tran(netlist = net, start=0, end=1e-3, output=out)
(or)
sim = Tran(net, out)
sim.setStart(0)
sim.setEnd(1e-3)

results = sim.run()

meas = Measure(results)

(ttrig, vtrig) = meas.tcross(signal=net.subckt1.net2,
threshold=net.subckt1.net1, direction=meas.rising, count=1)
print meas.avg(net.xsubckt1.net1, from=ttrig, to=(ttrig+0.1e-3))

-R.
