Transient Analysis and Pattern Generation with the HERON-IO2 Module


  • Standard IP to perform high speed capture of data into a buffer internal to the FPGA.
  • Standard IP to perform continuous waveform generation from a buffer internal to the FPGA.
  • VHDL sources so that you can add your own FPGA design to this interface which uses only a very small proportion of the FPGA resources

When combined with this standard bitstream, the HERON-IO2 provides a 511 sample capture buffer inside the FPGA. Via the Heron Serial Bus, a command can be issued to capture a buffer of between 1 and 511 samples, which will then be made available via the HERON FIFO. The HERON FIFO number to be used is programmed using HSB. Data is digitised by both A/D channels at 100Mhz

This part of this IP is useful for capturing bursts of high speed data, that can be analysed offline by a DSP or Host machine. This makes it ideal for a Transient analysis type application.

For the D/A side this IP provides a 512 sample SRAM buffer for each of the D/A channels. Data will be read from this SRAM at 100Mhz. The SRAM can be written with a pattern at any time using a HERON FIFO. The FIFO number to be used can be programmed via HSB.

This part if this IP is useful for using a DSP or Host computer to calculate off-line, the wave shape that is required. It can be written slowly into the SRAM buffer but will then be replayed in a loop at 100Msps. This makes it ideal for programmable pattern generation applications.
