10.1.10.4 Linear Binary Counters - IGLOO®, ProASIC® 3, SmartFusion® and Fusion Implementation Parameters
The following table lists the implementation parameters for a Linear Binary Counter.
| Parameter | Value | Description |
|---|---|---|
| LPM_HINT | TLACNT | Register look ahead model |
| COMPCNT | Compact model |
The following table describes the functionalities of a Linear Binary Counter.
| Data | Aclr | Enable | Sload | Clock | Up down | Qn+1 | Tcnt n+1 |
|---|---|---|---|---|---|---|---|
| X | 0 | X | X | X | X | 0's | 0 |
| X | 1 | X | X | f | X | Qn | Qn+1 = 2width-1 |
| X | 1 | 0 | 0 | f | X | Qn | Qn+1 = 2width-1 |
| m | 1 | X | 1 | f | X | M | Qn+1 = 2width-1 |
| X | 1 | 1 | 0 | f | 1 | Qn+1 | Qn+1 = 2width-1 |
| X | 1 | 1 | 0 | f | 0 | Q | Qn+1 = 2width-1 |
Note: Assume that Aclr is active low, Enable is active high, Sload is active high, Clock is rising and Tcnt is active high.
