This section covers the clocking guidelines for Dynamic Function eXchange (DFX) designs. In general, clocks in a DFX design are categorized as internal clocks and boundary clocks:
- Reconfigurable module internal clocks
- Clocks with driver and loads inside the reconfigurable module (RM).
- Boundary clocks
- Clocks with nets crossing the cell boundary of the
reconfigurable module as follows:
- Driver in the static region and loads in the RM
- Driver in the RM and loads in the static region
- Driver in the static region and loads distributed between RM and static region
- Driver in the RM region and loads distributed between RM and static region
The following figure shows an example of the different boundary clocks.
