This paper introduces a convenient, code-based option for loading Arbitrary Waveform Generator (AWG) patterns using the SupportCodes MFLApp RampsLoader. Traditionally, the ATE (Automated Test Equipment) AWG Pattern Editor has been the standard tool for creating AWGs. However, when more than 10 AWGs are required for a test application, the default ATE AWG Pattern Editor becomes cumbersome, tedious, and slow, complicating the preparation process. Collaborative efforts among multiple engineers often lead to AWG file conflicts, resulting in file corruption and significant time loss due to recompilation, even for minor changes. Frequent addition and modification of AWGs are integral to the development and debugging process. This presentation will detail the use of the SupportCodes MFLApp RampsLoader, including code examples to create 16x Battery Management System (BMS) cell voltages with AWGs and actual scope captures. The potential applications for the SupportCodes MFLApp RampsLoader are vast and limited only by one’s imagination. Additionally, the implementation of SupportCodes MFLApp RampsLoader enhances workflow efficiency by providing a streamlined and automated method for AWG pattern creation and management. This not only reduces the likelihood of human error but also significantly cuts down on development time. The capability to seamlessly integrate this loader into existing testing frameworks ensures minimal disruption while maximizing productivity. By leveraging this tool, engineering teams can focus more on innovative problem-solving and less on the mechanical aspects of AWG pattern generation.
