What is Exostiv Blade usage?
Exostiv Blade is utilized for software deployment on FPGA prototypes, pre-silicon validation, and pre-production tests of SoC prototypes and FPGA systems, capturing extensive data directly from running FPGAs.
It aids electronic engineers in scenarios such as:
- Realistic testing environments
- Performance verification
- Regression testing for IP revisions
- Debugging issues not detected during simulation
A flexible architecture
Exostiv Blade is composed of a chassis equipped with one or multiple capture boards. This architecture enables many configurations that adapt to the capture scenario.
Multiple FPGAs from multiple boards can be instrumented with capture IP instance that sample data directly from the design. Each of these instances use from 1 to 4 FPGA transceivers connected to the Exostiv Blade capture boards. The capture boards feature multiple quad tranceiver inputs in QSFP28 form factor used to transport the sampled data from the FPGAs under test to the Exostiv Blade hardware. A storage memory is attached to each of these connectors to receive and store the data.
This principle allows an extremely flexible scaling:
- Any number of FPGA chips from any number of boards can be instrumented.
- Each FPGA can contain multiple capture IPs.
- The Exostiv Blade unit is based on compact, tower, 2U to 4U chassis
- Depending on the chassis, from 1 to 10 capture boards can be used in the Exostiv Blade unit.
- Each capture board features 4x QSFP28 connectors, providing up to 4x 112.5 Gbps bandwidth using up to 16 transceivers.
- Each QSFP28 connector is attached to 16 GB up to 64 GB memory for trace storage, enabling very deep capture capabilities.

Exostiv Blade IPs overview
Exostiv Blade offers a range of IP types tailored to accommodate diverse capture scenarios.
Exostiv Blade Standard IP offers unparalleled flexibility, heightened interactivity in capture scenarios, and the fastest sampling speed, reaching up to 800 MHz.
With Exostiv Blade Extended Width IP, users can achieve the widest reach of up to 65k nodes while minimizing the impact on FPGA resources. By integrating multiple instances of either Exostiv Blade IP, users can expand their node coverage even further within a single or across multiple FPGAs. Each IP instance uses from 1 to 4 FPGA transceivers.
Standard IP
Main features include:
- Multiple capture unit with distinct sampling clock source
- Sampling up to 800 MHz
- Up to 16 x 2K bits simult. sampling per IP core instance
- Multiple data groups with dynamic selection at runtime
- Dynamic triggering and data qualification conditions selection
- Cross-clock domain triggering
- Trigger positioning across the whole Exostiv Blade capture memory
- BRAM-based and Streaming (DDR based) modes of captures
Extended Width IP
Main features include:
- Single capture unit to minimze resources and increase reach.
- Sampling up to 109 MHz
- Up to 65K bits simult. sampling per IP core instance
- Dynamic triggering
- Multi-instance trigger controls
- Trigger positioning across the whole Exostiv Blade capture memory
- Simplified streaming (DDR based) mode of capture
- Extremely small footprint – (typ: 0.80 % LUT + 0.95% REG of VU19P for 65K nodes)
Exostiv Blade IPs are configured, generated and inserted with the Exostiv Blade Core Inserter software. Exostiv Blade Core Inserter includes controls used to:
- Select the IP type.
- Define the location and settings of the FPGA transceivers used by the IP instance.
- Define the features and FPGA resources used by the IP.
- Set up the inputs ports of the IP instance and possibly select the observed nodes from the design under test.
- Generate and potentially insert the IP core into the target design.
IP insertion flows
- RTL level: Exostiv Blade IP instances are generated as a synthesized netlist with a VHDL or Verilog wrapper, design constraints and insertion template. The IP is inserted into the target design by the user like any other part of the design. Afterwards, the whole design has to be synthesized and implemented by the user. This mode of insertion provides full control to the user for insertion in the source code.
- Netlist level: (AMD FPGA only) Prior to proceeding with this type of insertion, the user has to load a post-synthesis design checkpoint in the FPGA vendor tool. Exostiv Blade Core Inserter interacts with the vendor tool to select the sampling clock signals and the nodes to be observed with the Exostiv Blade IP instance. Thereafter, Exostiv Blade IP instances are synthesized and automatically inserted into the target design netlist. This is followed by automatic or manual implementation (P&R) and bitstream generation.
- ECO (Engineering Change Order – AMD FPGA only): This special level enables late modifications of the connections between a specific IP instance and the design under test. Prior to proceeding with it, the user has to load a post place and route DCP into the vendor tool. Exostiv Blade core inserter interacts with the vendor tool to modify the existing connections with the FPGA under test. When the Exostiv Blade IP resources need not to be modified, this mode provides the fastests turnaround time to observe new sets of FPGA nodes.
