System Monitor - Digilent Genesys Reference Manual

Genesys Reference Manual
Pmods use 2x6 right-angle, 100-mil connectors that mate with standard 2x6 pin headers available
from a variety of catalog distributors. Each 12-pin Pmod connector provides two VCC signals (pins 6
and 12), two Ground signals (pins 5 and 11), and eight logic signals. VCC and Ground pins can
deliver up to 1A of current, and a jumper block is available for each connector to choose the VCC
voltage: regulated 3.3V or the unregulated board input voltage (VU). Pmod data signals are not
matched pairs, and they are routed using best-available tracks without impedance control or delay
matching.
Digilent produces a large collection of accessory boards that can attach to the Pmod and VHDC
expansion connectors to add ready-made functions like A/D's, D/A's, motor drivers, sensors, cameras
and other functions. See

System Monitor

The Genesys board supports the dedicated analog inputs (VP and VN pins on J13) to the Virtex 5
FPGA System Monitor block. The PCB layout for the VP and VN pins is designed using differential
pairs and anti-alias filtering in close proximity to the FPGA as recommended in the Virtex 5 FPGA
System Monitor User Guide. The Virtex 5 FPGA System Monitor function is built around a 10-bit, 200-
kSPS Analog-to-Digital Converter (ADC). The System Monitor is fully functional on power up, and
measurement data can be accessed via the JTAG port pre-configuration. The Xilinx ChipScope™ Pro
tool provides access to the System Monitor over the JTAG port. The System Monitor control logic
implements some common monitoring features. For example, an automatic channel sequencer allows
