Design, development and verification of measurement and control system aimed for high-power multi-output plasma power generators intended for PVD and PECVD processes. Enables outputs number modification during operation (through configuration registers) as well as at compilation stage (through implementation parameters – for resource usage reduction). The designed architecture supports multiple devices (with any number of outputs) connection for synchronization and cooperation.

Basic information
Generated waveform parameters (pulse width, frequency, amplitude, etc.) can be updated on the fly – whether a single generator or a multiple number of synchronized devices are used.
A generator output number is a maximum number of independent waveform generated ad the same time using a single physical device with separate electrodes. From the user standpoint, X output generator behaves like X separate generators encased in a single device.
Multi-output device (with more than 1 physical output) can be reconfigured to a single-output device in one of two ways:
- Update configuration registers’ values – no recompilation required
- Update implementation parameters and recompile the design – for reduced resource usage
Depending on the actual configuration, the control system’s parameters are automatically set and configured for expected behavior – including output control signals and measurements.
Based on the designed system architecture, at least 4 separate products (2 of which in multiple configurations) have been produced in a number of copies.
