Improve names of nets connected to RTM connector
-
FPGA_CLK1 and FPGA_CLK2 on the RTM sheet is confusing. There are other FPGA_CLKs on the schematics, not related to RTM, so one can be easily fooled (like me) by this overlap.
-
RTM_GTP03 and RTM_GTP47 are clocks, but the net name looks very much like MGT lines. It is even more confusing on the harness (GTP03 and GTP47).
-
RTM MGT names suggests the RTM will host SFPs, which may be not true, for instance with JESD data converters.
Instead of suggesting improvements to items 1, 2, 3 individually I would suggest following strictly the same names as in DESY Zone 3 Recommendations.
Some examples to illustrate these modifications:
- FPGA_CLK1_P -> GTP4-7_CLK_IN_P (or GTP47_CLK_IN_P)
- RTM_GTP47_P -> GTP4-7_CLK_OUT_P (or GTP47_CLK_OUT_P)
- SFP1TX_P -> GTP0_RX_P
- SFP8TX_P -> GTP7_RX_P
- On harness RTM_CLK: GTP03_P -> GTP0-3_CLK_OUT_P (GTP03_CLK_OUT_P)
