| CAUSE: | The Quartus II software cannot implement the carry or cascade chain that starts with the specified logic cell because there are not enough routing resources to route the carry or cascade chain secondary input signals. In FLEX 10KE devices, a carry or cascade chain is placed in LABs such that each LAB uses no more than two clock signals, one asynchronous clear signal, and one signal used as a clear or asynchronous load signal. |
| ACTION: | Modify the design so that the carry or cascade chain can be placed so that each LAB uses no more than two clock signals, one asynchronous clear signal, and one signal used as a clear or asynchronous load signal. |
