2.1.3 Host Communications
MON960 allows you to communicate and download programs developed for the Cyclone EP across a
PC’s serial, parallel, or PCI interface and a UNIX workstation’s serial interface. The Cyclone EP
supports two methods: Terminal emulation and Host Debugger Interface Library (HDIL).
2.1.3.1 Terminal Emulation Method
Terminal emulation software on your system communicates to MON960 on the Cyclone EP via an RS-
232 serial port. Serial downloads via terminal emulation require an intelligent host computer that
supports XMODEM (a standard transfer protocol). General system requirements are:
• DOS-based computer with PROCOMM*, CROSSTALK* or other telecommunication programs
• UNIX* workstation with an external serial port (e.g., SUN*)
Configure the serial port for 1200-115200 baud, 8 bits, one stop bit, no parity.
2.1.3.2 Host Debugger Interface Library (HDIL) Method
The MONDB.EXE utility, provided with MON960, allows you to download, execute and debug an
application program on the Cyclone EP. This utility differs from standard terminal emulation programs
in that it allows you to download executable images through a serial or parallel port, or via the PCI bus.
When using the serial port, the MONDB.EXE utility supports the standard baud rates (from 1200 to
115200 baud) to communicate and download to the Cyclone EP. Downloading via either the parallel
port or PCI bus is typically much faster than a serial port; actual performance depends on your system’s
hardware capabilities. Refer to MON960 Debug Monitor User’s Guide for detailed information.
2.1.3.3 Source Level Debugger
You may use a source-level debugger, such as Intel’s DB960, GDB960 or other, to establish serial
communications with the Cyclone EP. The MON960 Host Debugger Interface Library (HDIL) provides
the interface between MON960 and these types of debuggers.
2.1.4 Power Requirements
The Cyclone EP requires a stable power source of at least 3.5 A at +5 VDC. The included power supply
meets these requirements and connects to J7. If a card is designed for the expansion bus which requires
more than 1.0 A, you need to obtain a suitable power supply. To program FLASH devices, you must
supply a FLASH programming voltage through J6. J6 uses a standard PC-AT power connector pinout
that provides +5 VDC and +12 VDC to the board. J7 provides +5 VDC only. See Figure 3-1, Cyclone
EP and PCI-SDK Platform Physical Diagram (pg. 3-1), for J6, J7 locations.
The PCI-SDK Platform draws power from the PCI bus; it does not require an external power source.
The PCI bus also provides the voltages needed for FLASH programming.
