Category: Reveal
Tool: Diamond
Device: CrossLink

CrossLink does not have a dedicated JTAG port. Inserting the LA function configured with Reveal Inserter automatically embeds a circuit that emulates the JTAG interface. At this time, Reveal operates as a JTAG pin function using four general-purpose I/Os. Before executing the MAP Design process, assign the four automatically inserted "JTAG_TDO/_TDI/_TMS/_TCK" pins to the intended pins (if not specified, the tool will automatically perform the placement process).

Please note that TCK must be assigned to the dedicated clock input pin (PCLK_T pin). Also, CrossLink does not support Multi-voltage Input, so be careful with pin designation and board design so that the Vccio of the I/O bank to which these four signals are assigned is the same.
