Unfortunately, there is no project for KC705, there are for ZC706, kcu105, zcu102. - user1155120. "Add I/O Buffers" is -iobuf, while -fsm_style is the com-mand-line version of "FSM Style" (list). The possible values for the location constraint are all the external port identifiers (e.g., A8, M5, AM6, etc.). Due to the system's memory interface bandwidth limitation, there are intermediary . Else you can also follow the classical way to code a Bi-DirectionalBuffer such that Vivado infoes an IOBUF. Migrating to Achronix FPGA Technology (AN023) November 19, 2020 www.achronix.com 5 Figure 1: Synplify Pro and ACE Tool Flow Feature Comparison The combined Achronix tool flow supports all the features that a user would expect from a fully-fledged, mature, Updated HSTL_ II_T_DCI and HSTL_ II_T_DCI_18. The ALT_IOBUF primitive allows you to do the following: Make a drive strength (current strength) assignment. UG615 recommends inference for these, so I simply assigned the pins to 'Z' (this is a first test). This library is used during functional simulation and contains descriptions for all the device primitives, or lowest-level building blocks. there is an IO_BUFFER_TYPE attribute that you can apply to top level ports to avoid instantiation. This has one port IO that connects to the pin and three ports I, O and T that connect to your design in the fabric.. Each tool is invoked using the TCL "process run" com-mand, as shown in Figure 4. Notice that the P and N channels are included in the primitive (I = P, IB = N). IIRC, you can also specify something like -io_buf in additionally synthesis . locate comp "clk100m" site "aj14" ; iobuf port "clk100m" io_type=lvds25 ; This constraint locates the signal "CLK100M" to pin "AJ14", and ensures that a 2.5V LVDS input buffer is being used.
