The Galao Development Kit is a readout system used to access and work with IDEAS ROICs (readout ICs). The kit consists of all the hardware, firmware and software needed for ROIC control and readout. It supports several IDEAS ROICs with different functionality and interface methods. The system consists of following main components:
- Galao board: General purpose control board with control and readout circuitry
- ROIC test board: Interchangeable ROIC-specific board
- IDEAS Testbench: Software for controlling the boards and ROIC
The Galao board includes a digital core pre-installed IDEAS firmware, a calibration circuit for charge injection, trigger receivers, bias generators, and an analog receiver with 14-bit data ADC. It is powered by a single 5 V supply, and controlled via Ethernet.
The ROIC test boards contain wire-bonded ROICs and circuitry needed for the specific ROICs, as well as test points for all key ROIC signals. The boards also have front-end connectors for detectors, simplifying testing of the ROIC together with the intended detector. Schematic of the board is delivered along with the Galao ROIC Development Kit, giving the possibility to use it as basis for the design an application-specific ROIC readout system.
IDEAS Testbench is the control and readout software created by IDEAS. It allows for configuration of ROICs, readout with data being presented in plots while being obtained, and data logging to file. It also has an integrated Python interpreter for customized ROIC control and readout functionality. IDEAS Testbench is supported by Windows and Linux.
