You have two boards: one is PMC mezzanine board and this board is placed at second (carrier board). You want use jtag interface between this two boards.
Is signal TDI input or output at carrier board?
At PCI and PMC standards I didn`t find explicit description of direction this signals.
Thank you very m

In P&R, the jtag (boundary) cells are always placed as close as possible to the I/O pad. This make sense as the jtag cell are connected to the pad.
My question is beside connectivity requirement, is there other requirement that make it important to place the jtag cell as close to the IO pad as possible? Is there (...)

As we know, if we instantiate the core generated by Core generator of Xilinx, the timing performance will improve dramatically. However, as our design including the hdl codes except the core of Coregen should be processed by synthesis tools, Synplify, and the tools often depend on the timing-driven method to optimize the design, how could we offer
