Method for emulating a Boolean network system
First Claim
1. A method for emulating a Boolean network system having a plurality of input variables and a plurality of logic controlled outputs, the method comprising the steps of:
- (a) providing a plurality of inputs, each input adapted to be identified with a user selected one of the input variables to the Boolean network system, each input further adapted to assume a user selected logic state, said step comprising the steps of;
(i) providing each input as a manually controlled switch;
(ii) providing circuitry in association with each switch such that the switch is user operable to produce either a low or a high logic level signal; and
,(iii) providing a visual display for identifying to a user the Boolean network input variable each switch represents;
(b) providing a plurality of output indicators, each output indicator adapted to be identified with a user selected one of the logic controlled outputs of the Boolean network, each indicator providing an indication of the logic state applied thereto; and
(c) providing logic control means, said logic control means being programmable by a user to define a Boolean functional relationship between the user selected inputs and outputs such that the logic control means responds to the user selected logic states at the selected inputs to apply appropriate states to the selected outputs in accordance with a programmed Boolean functional relationship.

Abstract
Switches, manually operable to produce a desired logic signal level, are user assigned to represent the various variable inputs to a Boolean network. Indicators are user assigned to represent the logic state of outputs from the network. Process logic is user programmable to define the Boolean and sequential logic relationships between the assigned inputs and outputs. A visual display identifies to a user the input variable assigned to each switch and the logic output assigned to each indicator.
A user may analyze the operation of the Boolean network being emulated by monitoring output indicator status in response to logic level inputs selected by the switches.
