Signaltap and Chipscope

The JTAG port is responsible for the internal testing of the chip, with TMS (Chip mode selection), TDI (data input), TDO (data output), TCK (test data clock).

When the sampled clock detects the measured signal, the sampled data is stored in the internal ram of the FPGA, and the measured data is displayed in the window.

SIGNALTAP first hardware connection, then select the sampling clock, under the filter, generally choose post-compliation (after synthesis), select the sampling depth. Double-click the signal area to select the sampled signal, save to the project directory, and run the compilation. Select Load file, run

Chipscope first creates a new CDC file, then sets the trigger parameters, next,modify connections,make connections. Then save, and then compile the analysis Chipscope
