Key Features
Overview
The Total Phase eSPI Analysis Application for the Promira™ Serial Platform is the industry's first eSPI bus monitor, designed specifically for capturing, displaying, and analyzing eSPI communication between multiple devices in true real-time. When combined with Data Center™ Software, users gain live visibility into eSPI data traffic, enabling efficient debugging and protocol analysis
This software application must be installed on the Promira Serial Platform hardware to function. In addition to non-intrusive eSPI monitoring, Total Phase provides eSPI Active Example Files for all Promira devices equipped with SPI Active (Levels 1–3) licenses. These examples allow users to simulate eSPI activity, with supported performance that matches each device’s licensed SPI Active capability. Note: The eSPI Active Examples feature requires the relevant SPI Active license; units without these licenses do not support eSPI active examples.

The Promira eSPI Analysis Application (TP601010) turns a Total Phase Promira Serial Platform into an eSPI protocol analyser that monitors Enhanced Serial Peripheral Interface traffic at 20, 25, 33, 50 and 66 MHz in single, dual and quad I/O. It follows the peripheral, virtual wire, out-of-band and flash channels, with two slave selects, two alert lines and two reset lines, and adds match triggers, hardware filters and statistics. It is for firmware, BIOS and BMC teams validating eSPI links between a chipset and its EC, BMC or Super I/O.
eSPI Capture to 66 MHz in Single, Dual and Quad I/O
eSPI replaced the LPC bus on Intel platforms, and its traffic needs a dedicated eSPI protocol analyser rather than an SPI one. This application captures every supported eSPI clock rate up to 66 MHz across single, dual and quad I/O, so you see the link at the configuration the platform actually negotiates.
Peripheral, Virtual Wire, OOB and Flash Channels
The analyser decodes the eSPI channels that carry a platform conversation: peripheral cycles, virtual wires that replace legacy side-band signals, out-of-band messages to a BMC, and flash access. Monitoring two slave selects, two alert lines and two reset lines alongside the data shows the whole exchange during boot, sleep transitions and resets, not one channel in isolation.
Triggers, Hardware Filters and Statistics
Match triggers start a capture on the transaction that matters, and hardware filters discard traffic you do not need before it reaches the PC. Hardware statistics counters summarise the traffic, which helps make sense of a heavy boot sequence. Captures are viewed in Total Phase Data Center, which supports the Promira eSPI analyser from version 6.62. The analyser decodes the initialisation handshake and channel negotiation, and reports both correct and incorrect CRC values for command and response phases. For automated capture, the free Promira Software API eSPI Analysis drives the analyser from C, C#, Python, .NET, VB.NET or VB6.

Limitations
- This is a software licence only. It runs on the Promira Serial Platform (£1,040 ex VAT), which is sold separately and must be in place before the licence can be installed.
- eSPI I/O runs at 1.8 V, which is the eSPI norm. If your target runs eSPI at 3.3 V, contact us before ordering.
- Monitor only. It does not act as an eSPI master or slave.
Licence or Kit?
| eSPI Analysis Application | Promira eSPI Bus Analyser Kit | |
|---|---|---|
| Order code | TP601010 | TP601100 (Debug Store kit) |
| Contents | Licence for an existing Promira | Promira Serial Platform with the eSPI Analysis application |
| Price ex VAT | £1,215 | £2,130 |
If you do not yet own a Promira, the Promira eSPI Bus Analyser Kit supplies the platform and this application together for £2,130 ex VAT; bought separately, the two total £2,255 ex VAT. Choose this licence on its own to add eSPI to a Promira you already use for I2C or SPI.
Typical Applications
Tracing virtual wire and OOB traffic between a PCH and an embedded controller during S3 and S5 transitions. Debugging BMC firmware that misses an eSPI alert during boot. Verifying flash channel accesses on a platform where the EC shares the BIOS flash.
eSPI Analysis suits BIOS and EC firmware engineers, platform validation teams and BMC developers working on Intel eSPI designs.

Frequently Asked Questions
Does this include the Promira hardware?
No. It is an application licence for a Promira Serial Platform you already own or order with it. The Promira Serial Platform is £1,040 ex VAT.
What eSPI clock rates does it capture?
20, 25, 33, 50 and 66 MHz, in single, dual and quad I/O.
Can it monitor a 3.3 V eSPI bus?
The analyser is specified for 1.8 V eSPI I/O. Contact us with your target details before ordering for a 3.3 V bus.
Which software do I need?
Total Phase Data Center, version 6.62 or later, which is free.
