Historically, commercial software for designing RF and microwave products at the circuit level matured before equivalent full-featured system level software became widely available. The gap between CAE (Computer Aided Engineering) tools at the circuit level and what was needed for designing at the system level was often filled by designers creating their own system analysis tools in spreadsheets, using common office software such as Excel. There were many drawbacks to the spreadsheet as system analysis tool. Their one-of-a-kind nature, narrow focus on the analysis of one type of problem, and the inability to track the creation and propagation of spurious signals and intermodulation products top the list of drawbacks.
