Standalone Clock Tree Synthesis Capabilities

Using the clock_opt command is the recommended method for performing clock tree synthesis and optimization with ICC. However, in cases where finer control is required, ICC also provides the following standalone clock tree synthesis capabilities:

- Clock tree power optimization
- Clokc tree synthesis
- High-fanout net synthesis
- Clock tree optimization
- Interclock delay balancing
- I/O timing adjustment

The script below provides an example of performing clock tree synthesis and optimization by using the standalone capabilities. The following sections provide details about these capabilies.
