Reply To: Create trial cells when using minimizer algorithm?

A decorator can clean up the code a bit like this:

def trial_cell(func):
    def wrapper(*args, **kwargs):
        cell = kwargs.pop('cell', False)
        if not cell:
            S1 = set(nd.cfg.cellnames.keys())    
        out = func(*args, cell=cell, **kwargs)
        if not cell: 
            S2 = set(nd.cfg.cellnames.keys())
            for s in S2 - S1:
                nd.cfg.cellnames.pop(s)
        return out
    return wrapper

@trial_cell
def cell_to_solve(offset=10, target_diff=20, cell=False):
    with nd.Cell('test') as C:
        m1 = demo.mmi1x2_dp().put(0)
        nd.trace.trace_start()
        demo.deep.sbend(offset=offset).put(m1.pin['b0'])
        demo.deep.sbend(offset=-offset).put()
        nd.trace.trace_stop()
        L1 = nd.trace.trace_length()
        m2 = demo.mmi2x2_dp().put()
        nd.trace.trace_start()
        demo.deep.sbend_p2p(pin1=m1.pin['b1'], pin2=m2.pin['a1']).put()
        nd.trace.trace_stop()
        L2 = nd.trace.trace_length()
        diff = L1 - L2
    if cell:    
        return C
    else:
        return diff - target_diff
