1. A programmable logic device, comprising:
- a system monitor, the system monitor including;
channel inputs including analog inputs;
selection circuitry coupled to the channel inputs, the selection circuitry having a channel output;
an analog-to-digital converter having an analog input and a digital output;
an interface having storage devices, the storage devices for storing control information and data, the interface including a dynamic reconfiguration port and control logic;
the analog-to-digital converter configurable responsive to a first portion of the control information;
the selection circuitry configured to selectively couple a channel input of the channel inputs to the channel output responsive to a second portion of the control information; and
the analog-to-digital converter coupled to the channel output at the analog input and coupled at the digital output to the storage devices.

Abstract
Method and apparatus for a system monitor (20) embedded in a programmable logic device (10, 50, 60) are described. The system monitor (20) includes a dynamic reconfiguration port interface (205) for configuring or reconfiguring the system monitor (20) during operation thereof. The system monitor (20) includes an analog-to-digital converter (200) which is reconfigurable responsive to input via a dynamic reconfiguration port (201).
