A method for verifying mask pattern data includes preparing design circuit data on a design circuit which realizes a desired electrical operation. The first node and the second node are both comprised within a wireless communication network. As a result, the productivity of film can be improved. The technology is particularly well-adapted to use in medical devices, including bioelectronic stimulators, where redundant devices are required for safety in case of single component failure while unacceptable levels of distortion may occur when conventional components are used. The common language files produced by the front end systems can be used in the common library.
