SSB: SRP List Explanation
1 . 1 . Introduction
Example
SRP (Service Re ference Protocol) is a softw are too l that creates a list w i th all refer e n c es to signal lines. The list contains
references to the signals w i thin all schemat ics of a PWB. It replaces the text refe r ences currentl y p r inted next t o the signal
names in the s
chematics. These printed refe rences are created man ually an d are t h e r efore n o t guar an teed to be 100 %
correct. In additio n , in the current crowded schema t ics there is often none or ver y little pl ace for these references.
Some of the PW
B schematics w ill use SRP while others w ill sti ll use the manual refe rences. Either there w
ill be an SRP
r e fer ence list for a schematic, or ther e w ill be pr inted r e ferences in the schematic.
1.2. No n - SRP Schematics
There a r e severa l different signals available in a schematic:
1.2.1. Po w e r Supply Lines
All pow er suppl y lines are available in t he suppl y line overview (see chapter 6). I n th e schematics (se e chapter 7) is n o t
indicated w h e r e supplies are coming from or going to.
It is how ever indi ca
ted if a supply is incoming (created elsew h e r e), o r outgoing (cr eat ed or adapt ed in the current sche m atic).
+5 V +5 V
Outgoing Incoming
1.2.2. Normal Signals
For no rmal signals, a schematic r e ference (e. g . B1 4b) is placed next to the signals.

1.2.3. Grounds
For no rmal and s pecial grounds (e .g. GN DH OT o r GND3V3 etc.), n o thing is indicate d.
1.3. SRP Schematics
SRP is a tool, w h ich automatically creates a list w i th signal reference s , indicating on which sc hematic t he signals are used.
A reference is cr eated for all signals indicat ed w i th an SRP s y mbol, these s y mbols are:
+5 V +5 V
Power suppl y li ne.
na m e na m e
Stand alone signal or sw itching li ne (used as less as possible).
na m e na m e
Signal line into a w i re tree.
na m e na m e
Sw itching line into a w i re tre e .
na m e
Bi-directional lin e (e.g. SDA ) into a w i r e tree.
na m e
Signal line into a w i r e tree, its dir e ction depends on t he circuit (e.g. ingoing for PD P, outgoing for L C D sets).
Remarks:
• When there is a black dot on the "signal dire ction arrow" it is an SRP symbol, so there will be a reference to the signal
name in the SRP list.
• All references to normal grounds (Ground symbols without additi onal text)
are not listed in the reference list, this to keep
it concise.
• Signals that are not used in multiple schematics, but only onc e or several times in the same schematic, are included
in the SRP reference list, but only with one reference.
Additional Tip:
When using the PDF service manual file, you can very easily search for signal names and follow the signal over all the
schematics. In Adob
e PDF reader:
• Select the signal name you want to sear ch for, with the "Select text" tool.
• Copy and paste the signal name in the "Search PDF" tool.
• Search for all occurrences of the signal name.
• Now you can quickly jump between the different occurrences and follow the signal over all schematics. It is advised to
"zoom in" to e.g. 150% to see clearly, which text is select
ed. Then you can zoom out, to get an overview of the complete
schematic.
PS. It is recommended to use at least Adobe PDF (reader) version 6. x, du e to better search possib ilities in this vers ion.
