3.2 Getting Started
3.2.1 Configuring the Jumper settings
Morph-IC-II module has two jumpers labelled VBUS and V_BANK4.
A summary of the jumper functions is given in Table 1.
NOTE: When using V_BANK4, care must be taken regarding this jumper; if there is a large enough
discrepancy between the voltage that powers an IO Bank and the logic high voltage of the signals
processed by the bank damage can occur.
3.2.2 Configuring the FPGA
The Morph-IC-II package includes a *.RBF loader programme called “MorphLd”. This programme is used
to load RBF files into the FPGA of Morph-IC-II via the USB to Passive Serial interface. These *.RBF are
synthesised HDL (VHDL or Verilog) code with additional settings for the FPGA specified by the Quartus-II
options. These files are generated when a HDL project is compiled using (suitably configured) Quartus-II
or a similar HDL compiler. Using this utility along with Quartus-II the HDL code of an application can be
compiled and exported to Morph-IC-II.
(See AN_141_MorphIO-II and MorphLd Utilities for Morph-IC-II)
1) Jumper VBUS connects USB connector pin 1 to J1-1.
2) Jumper V_BANK4 connects 3V3IO to the power supply pins of Bank 4.
A) When jumper VBUS is closed, the Morph-IC-II module is powered from the USB bus. This
B) When jumper VBUS is open, the Morph-IC-II module requires an external voltage supply of 5
A) When jumper V_BANK4 is closed, a short is formed between 3V3IO and V_BANK4. This
B) When jumper V_BANK4 is open, an external voltage supply must be applied to J2-29 and J2-
connects the VBUS power from the USB host PC to the voltage regulator input of Morph-IC-II.
This voltage regulator provides power to the following: VCC3V3, VPLL and VUSB all of which
power the FT2232H chip. This mode is known as “bus powered mode”.
Volts DC applied to J1-1. This mode is known as “self powered mode”.
connection provides 3.3 volts to I/O Bank 4 of the FPGA.
NOTE: When this jumper is closed J2-29 and J2-30 must be unconnected or
connected to a 3V3 supply (this is the case for typical MorphIC-1K application
boards).
