The traditional dilemma for performing network simulations with
analog circuits is the great difficulty of handling the connectivity
in hardware. The main problem is that hardware-based connectivity
must be built following predefined plasticity and connectivity rules,
and that once the hardware is built, it is usually not possible to
change its configuration. We show here an alternative system in
which the membrane equations are solved in analog ASIC circuits, but
the connectivity remains controlled by a digital computer. We
illustrate the behavior of this system by comparing the analog
simulations with traditional computer simulations of the same models.
