Platform Cable USB II
iMPACT 7.1i (and later) provides a feature wherein the BSDL file of each device in a target JTAG chain is scanned to
determine the maximum Boundary-Scan clock (JTAG TCK) frequency. iMPACT 7.1i (and later) automatically restricts the
available TCK_CCLK_SCK selections to frequencies less than or equal to the slowest device in the chain. By default,
iMPACT 7.1i (or later) selects either 6 MHz or the highest common frequency when any device in the JTAG chain is not
capable of 6 MHz operation. Table 3 shows the maximum supported JTAG TCK frequency for a variety of Xilinx devices. See
the device data sheet or BSDL file for maximum JTAG TCK specifications.
Note: Certain Xilinx design tools and iMPACT versions earlier than 7.1i do not restrict the TCK_CCLK_SCK selections in JTAG mode.
Accordingly, users should take care to select a TCK_CCLK_SCK frequency matching the JTAG TCK specifications for the slowest device
in the target chain.
In Slave Serial or Direct SPI Configuration mode, the TCK_CCLK_SCK speed can be set to any one of the available
selections. By default, the TCK_CCLK_SCK speed is set to 6 MHz. Users should take care to select a TCK_CCLK_SCK
frequency matching the Slave Serial clock (CCLK or SPI clock) specification of the target device.
