Dynamic Reconfiguration (ALTGX_RECONFIG Instance) Resource Utilization
You can observe the resources utilized during dynamic reconfiguration in the
ALTGX_RECONFIG MegaWizard Plug-In Manager. This section contains an estimate
of the logic elements (LE) resources utilized during dynamic reconfiguration.
You can obtain resource utilization for all other PMA controls from the
ALTGX_RECONFIG MegaWizard Plug-In Manager.
For example, the number of LEs used by one dynamic reconfiguration controller is 43
with only tx_vodctrl selected. Similarly, the number of registers is 130.
Figure 2–60 shows the resource utilization in the ALTGX_RECONFIG MegaWizard
Plug-In Manager.
