Xilinx® documentation is organized around a set of standard design processes to help you find relevant content for your current development task. All Versal® ACAP design process Design Hubs and the Design Flow Assistant materials can be found on the website. This document covers the following design processes:

System and Solution Planning
Identifying the components, performance, I/O, and data transfer requirements at a system level. Includes application mapping for the solution to PS, PL, and AI Engine.

The technical reference manual (TRM) describes the overall hardware architecture of the Versal ACAP and provides details on the blocks in the platform management controller (PMC) and in the processing system (PS). The PS includes the real-time processing unit (RPU), application processing unit (APU), and their peripherals.

There are several device families with different device options. The availability of a specific device option is listed in the Versal Architecture and Product Data Sheet: Overview (DS950). The TRM usually identifies these with the designation: device option.

Embedded Software Development
Creating the software platform from the hardware platform and developing the application code using the embedded CPU. Also covers XRT and Graph APIs.

Embedded software runs in the RPU and APU scalar engines located in the PS.

The PMC and PS functional units require device drivers as part of the embedded software stack. Several TRM reference sections focus on content for device driver development. The PMC, RPU, and APU peripherals are described in the following sections:

The boot hardware modes and functionality are described in the Platform Boot, Control, and Status section of the TRM. Additional TRM sections and chapters describe the interconnect, timers, counters, clocks, resets, and power.

The system software boot up and operating system environments are described in the Versal ACAP System Software Developers Guide (UG1304). The PMC modules are described in the Embedded Processor, Configuration, and Security Units section.

Board System Design
Designing a PCB through schematics and board layout. Also involves power, thermal, and signal integrity considerations.

The TRM includes some important information to help with board design planning and development.

For package and pin information, see the Versal ACAP Packaging and Pinouts Architecture Manual (AM013).

The electrical specifications are provided in the Versal Prime Series Data Sheet: DC and AC Switching Characteristics (DS956) and the Versal AI Core Series Data Sheet: DC and AC Switching Characteristics (DS957).
