Overview

The DLL sample application demonstrates the clock doubling capability of DLLs and DCMs. The user specifies a frequency for the local bus clock on the command line. The application programs the local bus clock generator to the specified frequency, which is doubled and used to clock a 32-bit counter. The application reads the counter once per second, displaying the difference between the current and last readings.

Syntax
dll [options ...] <frequency>
Options

Option Argument type Meaning
-card base 10 integer ID of card to open
-index base 10 integer Index of card to open

FPGA Design

The DLL sample application makes use of the DLL sample FPGA design (Verilog, VHDL).
