eSRAM Intel FPGA IP
Product Information
The product is the Intel FPGA IP, which is compatible with the Intel Quartus Prime Design Suite software. The IP has different versions that match the software versions until v19.1. Starting from software version 19.2, a new versioning scheme is introduced for the Intel FPGA IP.
The IP versions are as follows:
| Version | Date | Intel Quartus Prime Version | Description | Impact |
|---|---|---|---|---|
| v20.1.0 | 2022.09.26 | 22.3 | Enabled Intel AgilexTM eSRAM IP system component |
connection
support in Platform Designer tool.| ISO 9001:2015 Registered
v20.0.0| 2021.10.04| 21.3| Updated the ch{0-7}_ecc_dec_eccmode and
ch{0-7}_ecc_enc_eccmode
parameters to ECC_DISABLED for unused ports.| IP upgrade is required to obtain
the design pass compilation
with Intel Quartus Prime Pro Edition software version 21.3.
v19.2.1| 2021.06.29| 21.2| Fixed the hold violation by adding (
altera_attribute = -name
HYPER_REGISTER_DELAY_CHAIN 100) to the eSRAM Intel Agilex FPGA
IP.| The change is optional. An IP upgrade is required if your IP
cannot meet the maximum performance specification due to a hold
violation.
v19.2.0| 2020.12.14| 19.4| Removed the dynamic ECC encoder and decoder —
bypass
feature.| N/A
v19.1.1| 2019.07.01| 19.2| Initial release for Intel Agilex devices.| N/A
If a release note is not available for a specific IP version, it means there are no changes in that version.
Note: The Intel FPGA IP version (X.Y.Z) number can change with each Intel Quartus Prime software version.

eSRAM Intel® Agilex™ FPGA IP
Release Notes
If a release note is not available for a specific IP version, the IP has no
changes in that version. For information on IP update releases up to v18.1,
refer to the Intel® Quartus® Prime Design Suite Update Release Notes.
Intel FPGA IP versions match the Intel Quartus Prime Design Suite software
versions until v19.1. Starting in Intel Quartus Prime Design Suite software
version 19.2, Intel FPGA IP has a new versioning scheme.
The Intel FPGA IP version (X.Y.Z) number can change with each Intel Quartus
Prime software version.
A change in:
- X indicates a major revision of the IP. If you update the Intel Quartus Prime software, you must regenerate the IP.
- Y indicates the IP includes new features. Regenerate your IP to include these new features.
- Z indicates the IP includes minor changes. Regenerate your IP to include these changes.

|---|---|---|
| 20.2 | Renamed the I/O PLL filename to waive the warning message from the IOPLL |
file.
If the two eSRAMs have the same PLL parameters (PLL reference clock frequency and PLL desired clock frequency), the warning message can be ignored.
If the two eSRAMs have different PLL parameters, after compilation they will be set to the same PLL frequencies taken from one of the eSRAM Intel FPGA IP parameters. Refer to the Quartus Fitter report ➤ Plan Stage ➤ PLL Usage Summary to observe the implemented eSRAM IOPLL frequencies.
IP update is needed when the PLL parameter for both eSRAM is different.
