DDS upgrade project meeting notes.
This page describes the outcomes and discussion points raised in
meetings between Creotech and CERN. The outline of the project is to:
- Create new schematics for a EDA-03010-v3.0.
- Generate a new PCB layout description.
- Provide a Production Test System (PTS) that can be used to validate
the cards that have been
manufactured.
Meeting 23/01/2019 - present Creotech (Mikołaj Sowiński), CERN (John Gill)
Items discussed:
- JG gave an overview of the project's direction, with the final goal
to produce a RFoWR starter kit. This kit will encompass hardware
(orderable from vendors like Creotech) and software packages that can
been downloaded from CERN to configure device drivers, firmware and
gateware (FPGA images). Working together, these hardware and software
components will provide users with a quick start guide to configuring
and controlling their RF distribution project.
- Creotech have not yet received notification that the contract has
been signed and accepted by CERN.
- ACTION: A1.1 - JG to seek clarification with EVB about the
status of the contract.
- Creotech would like access to the CERN Altium DRC rules (schematics
and layout) that are mentioned in DO-30550.
- ACTION: A1.2 - JG to provide Creotech with these documents.
- We discussed the need for both Creotech and CERN to place
documentation (e.g. schematic bundle) in a common place.
- ACTION: A1.3 - JG to investigate where CERN can place these
documents.
- JG enquired about the current status of the schematics. CERN received
an updated set of schematics from GK (09/01/19). This was reviewed at
CERN and comments attached. Is there a new set of schematics addressing
the issues raised?
- ACTION: A1.4 - MS to clarify the schematic status with
GK.
Meeting 30/01/2019 - present Creotech (Mikołaj Sowiński), CERN (John Gill)
Items discussed:
- MS gave an update from Creotec about progress. Creotech have received
6 prototype boards, manufactured according to the schematics and layout
received by CERN on the 14/01/2019. Creotech are starting to test and
update the PTS for this new design.
- Outstanding action items (A1.1, A1.2, A1.3 and A1.4)
- ACTION: A1.1 - JG to seek clarification with EVB about the
status of the contract.. DONE. Creotech have received the
contract.
* ACTION: A1.2 - JG to provide Creotech with the CERN Altium DRC
rules (schematics and layout) that are mentioned in DO-30550.
OUTSTANDING*. No documentation of these rules has yet been obtained.
A way forward is likely to involve CERN waiving this requirement and:
- Creotech will produce schematics and layout to their own professional
standards.
- BE-CO-HT will review deliverables and provide feedback until
agreement reached with Creotech.
- Deliverables passed to EDA, feedback from EDA relayed to Creotech.
- One suggestion is that additional hints regarding DRC may be inferred
from previous revisions of the boards.
- ACTION: A1.3 - JG uploaded and tagged the two releases received
from Creotech. DONE
- ACTION: A1.4 - MS to clarify the schematic status with GK.
DONE* MS seeked clarifaction of A2 and A4, they are just trival note
requests.
Additional items and discussions raised:
- ACTION: A2.1 - Creotech to monitor the temperature of the new
prototypes and provide preliminary feedback.
- ACTION: A2.2 - JG to update the documentation of the schematic
status table to clearly show status of all outstanding items.
- ACTION: A2.3 - MS to provide feedback on the requested changes
to the schematic (see A15, A16 and A17 of the schematic review).
- ACTION: A2.4 - JG to clean-up the repository, removing unwanted
directories and placing suitable .gitignore files.
- ACTION: A2.5 - JG to check the schematic regarding schematic
action A4 on the P3V3 power rail.
