# Overview

Qualcomm Insertion Loss Calculator is a web-based pre-simulation utility used to estimate PCB routing
insertion loss before using the Layout or SERDES Checker. It helps determine whether a proposed PCB
route meets the loss requirements for a selected chip and high-speed interface.

## Key features

- Selects target requirements by chip and interface.
- Accepts stackup data from an `.xlsx` template or direct table entry.
- Supports differential and single-ended lane calculations.
- Calculates the maximum routing length supported by a stackup and loss budget.
- Calculates total insertion loss across one or more PCB trace segments.
- Reports calculated loss and pass or fail status against the applicable budget.
