From 6519e1aed00bc04c2e786c42c50e8e66e1ecf2c3 Mon Sep 17 00:00:00 2001 From: Raphael Roth Date: Thu, 2 Jul 2026 14:06:14 +0200 Subject: [PATCH 01/34] [keymgr_dpe, otp_ctrl, rtl] Change otp keymgr_dpe interface Split the otp_keymgr_key interface into its respective components. Future version of the keymgr(_dpe) may receive the information from different IP's rather than combined from the otp_ctrl. To avoid a circular dependencies the DevIdWidth instantiated in keymgr_dpe_pkg replaces the otp_ctrl_pkg::DeviceIdWidth. As the keymgr still expects the combined message the earlgrey top manually combines the key material. This fix will be removed when the keymgr is replaced by the keymgr_dpe.

The secret / seed verification inside the otp_ctrl scoreboard template are no longer dynamically generated. The reason is that the previously shared port signal has been split into its respective components, which does not interacts well with the dynamic generation anymore. However, adding a secret to the otp now results in a port-list change anyways the resulting overhead is deemed acceptable.

Remove the `chip_sw_keymgr_derive_attestation` and the `chip_sw_keymgr_derive_sealing` as these tests cannot be ported directly.
