Bitstream File Generation Through ACE
ACE has a straightforward interface to generate the bitstream files required to implement all
of the supported configuration modes. The bitstream files will get generated in the ‘FPGA
Programming – Generate Bitstream’ step of the compilation flow.
The STAPL jam file needed for JTAG mode configuration will by default, always be
generated. The ‘Bitstream Generation’ section of the Project Options menu, shown in Figure
11 below, provides users with a menu selection to generate bitstream files for the other
configuration modes as well.

These bitstream file types are described in a little more detail below:
1. JTAG: STAPL .jam file for JTAG mode programming. There are options for
generating a single and a multi-device scan chain configuration file in which the scan
chain details need to be specified.
2. Serial Flash: A single serial flash (.flash) binary file. This is literally a full binary file
of the bitstream data that could be burned into a single flash memory. There are NO
newline characters in the file. It is completely binary.
