void xsi_trace_all(xsiHandle design_handle);
void Xsi::Loader:: trace_all();

Call this function after xsi_open to turn on waveform tracing for all signals of the HDL design. Running the simulation with waveform tracing causes the Vivado simulator to produce a waveform database (WDB) file containing all events for every signal in the design. The default name of the WDB file is xsim.wdb. To specify a different WDB file name, set the wdbFileName field of the s_xsi_setup_info struct when calling xsi_open, as shown in the example code.

Example code:

#include "xsi.h"
#include "xsi_loader.h"
Xsi::Loader loader("xsim.dir/mySnapshot/xsimk.so","librdi_simulator_kernel.so");
s_xsi_setup_info info;
memset(&info, 0, sizeof(info));
char wdbName[] = "test.wdb"; // make a buffer for holding the string "test.wdb"
info.wdbFileName = wdbName;

After the simulation completes, you can open the WDB file in Vivado to examine the waveforms of the signals. See Opening a Previously Saved Simulation Run for more information on how to view WDB files in Vivado.

Important: When compiling the HDL design, you must specify -debug all or -debug typical on the xelab command line. The Vivado simulator does not record the waveform data without the -debug command line option.
