Group 1 - Advanced Micro Devices, Inc. (AMD) has recently gained attention due to its quantum work and supply constraints affecting its product line, leading to a stock increase of 7.6% to a new high [1] - AMD manufactures semiconductors including CPUs, GPUs, and adaptive chips, with notable brands such as AMD Ryzen, Radeon, EPYC, Instinct, and Versal [1] - CEO Lisa Su is recognized for her strong leadership, emphasizing confidence in AMD's partnerships, particularly with OpenAI, which has placed significant orders for chips [1] Group 2 - While AMD shows potential as an investment, there are AI stocks perceived to have greater upside potential and lower downside risk [1]

Key Features of Unified Selective Device Installer (USDI) - AMD Vivado 2025.1 introduces the Unified Selective Device Installer (USDI) for efficient FPGA and SoC design [1][3] - USDI allows users to download only necessary device files, streamlining installation and workflow [3] - USDI consolidates Vivado, Vitis, and related tools into a single installer with selective device file downloads [4] - The Filter Device section streamlines device selection by allowing users to search by device name or series [6] - Users can select specific devices within a series, further reducing download size and enabling tailored selection [8] Benefits of USDI - USDI reduces download size and disk space usage by up to 60% [4][11] - Installation times are faster, and valuable disk space is saved, improving setup efficiency and system performance [6] - Tailoring the install speeds up the process, optimizes storage, and saves bandwidth [5] Specific Device Support and Examples - Selective installation currently applies to AMD Versal devices, allowing users to choose specific parts [4] - Downloading all devices from the Versal AI Edge Series in AMD Vivado 2024.2 required approximately 83 GB download size and 212 GB disk space [5] - With USDI, selecting all devices from the Versal AI Edge Series reduces the download size to 22 GB and disk space to 77 GB, a 60% reduction in download size [5] Offline Installation - USDI allows users to select specific devices for offline installation by downloading an image from the Web Installer [9] - Users can select "Download Image (Install Separately)" from the web installer setup and choose the required Versal devices [10]

Versal Clocking Architecture Enhancements - AMD Versal devices feature a segmented clocking structure, utilizing global clocking with regional or global load placement for efficient resource utilization and improved clock characteristics [4][5] - Versal architecture introduces BUFG Fabric for high-fanout routing with predictable delay and MBUFG for fast division of global clocks, reducing skew between synchronous clock domains [6][7] - Clock trees are more flexible for targeted skew reduction in multi-SLR devices, with calibrate deskew tuning clock distribution at startup [7][8] Clock Routing and Deskew Schemes - Versal employs a Vertical H-tree to minimize clock skew in both vertical and horizontal directions [12] - Basic deskew minimizes insertion delay, suitable for I/O interfaces and synchronous CDC paths with parallel BUFG [18] - Calibrated deskew, used in Versal SSIT devices, balances programmable delays during startup to minimize skew across the clock network [19][32] Calibrated Deskew Considerations - Calibrated deskew is off by default and should be enabled based on timing report analysis, particularly for large skew issues and maximizing SLR crossing performance [39][40] - Calibrated deskew is more beneficial in larger Versal SSIT devices with higher performance clocks (over 350 MHz) and numerous clock loads spanning all SLRs [42] - Avoid using calibrated deskew if synchronous CDC clocks employ parallel clock buffers, BUFG_FABRIC drives high fanout control signals, I/O interface clocks are used, or the clock root is in the GT column or VNOC columns [43]
