Vivado Software SOM Connector Abstraction
The SOM board les introduce a SOM connector abstracon that allows the hardware
conguraon to focus on SOM connector level physical mapping. This is intended to help
eliminate the need for the carrier card designer to have to create a physical pin translaon table.
The SOM connector infrastructure uses the convenon of: <connector name> + <_> +
<connector_pin_number>. For example, a SOM connector pin name of som240_1_c18
refers to the pin C18 of the SOM240_1 connector. Using this convenon and the XDC get ports
funconality, a carrier card constraints le can be described in terms of a SOM physical interface
when combined with a SOM constraint le that captures the Zynq UltraScale+ MPSoC to SOM
connector pin denion.
SOM Vivado Tools XDC Files
The SOM Vivado board le includes an XDC le that captures the Zynq UltraScale+ MPSoC
package mapping to SOM connector pin denions. This le can be used by the carrier card
designer to idenfy the full SOM plus carrier card design constraints.
A carrier card designer can also refer to the KV260 Starter Kit carrier card XDC les for an
example implementaon of a decoupled SOM and carrier card constraint denion.
