<variation_name>_icm Partition
When you generate a PCI Express IP core, the MegaWizard produces module,
<variation_name>_icm in the subdirectory
<variation_name>_examples\common\incremental_compile_module, as a
wrapper file that contains the IP core and the ICM module. (Refer to
Your application connects to this wrapper file. The wrapper interface resembles the
PCI Express IP core interface, but replaces it with an Avalon-ST interface. (Refer to
Table
The wrapper interface omits some signals from the IP core to maximize circuit
optimization across the partition boundary. However, all of the IP core signals are still
available on the IP core instance and can be wired to the wrapper interface by editing
the <variation_name>_icm file as required.
By setting this wrapper module as a design partition, you can preserve timing of the
IP core using the incremental synthesis flow.
