Synthesis

After incorporating the SnapShot macro into the design, the user will be able to synthesize the design with

the Synplify-Pro or Precision synthesis tool. After synthesis, the generated netlist can be imported into ACE

to generate the FPGA programming ﬁle (bitstream).

Setting Up the Bitporter Pod Connection

The following section describes how to conﬁgure the SnapShot Debugger view for communication with

an already-connected Bitporter and an already-programmed Achronix device. For details on physically

connecting the Bitporter pod/cables, please see the Bitporter User Guide (UG004).

In the SnapShot Debugger view, under ”BitPorter Connection” either select Automatically Detect Pod or

Specify Pod Name to choose which already-connected Bitporter pod will be used to communicate with the

already-running design on the Achronix device.
