Martin Schramm c56283aeee e1-tracer: update again from ice40 lib 
Another pin was found with 'wrong' direction state. Severity of this
is low as is shows only warnings in ERC, removing it anyways during
verification.

Martin Schramm 8ce574846d laforge.lbr: PULSE_T1094NL: better tPlace and tDocu layer (for OSM#3270) 2018-05-29 19:21:38 +02:00
Martin Schramm 69f96a69ad connect LIU's pin 44 to GND (solves OSM#3247) 2018-05-29 13:38:51 +02:00
Martin Schramm ed2b563216 laforge.lbr: repair PULSE_T1094NL footprint and symbol (solves OSM#3270) 
... and OSM#3271. - The transformer symbol is made of two identical coils
and hence it is not possible to mark the "2:" side (pins 9-11) separately.
But the naming of this coil was changed in a way, that, when invoked, the
"2" of the subpart name "TR1-1:2" shows towards the pins 9-11.
Maybe we should evolve to a device symbol with two coils merged rather than
two identical but separated, then an individual naming could honour the
2:1 side and can not be disturbed by e.g. subsequent mirroring. -
Also repaired the name and value designators' layer association.

Harald Welte cdbcff9b18 CRC4: use proper CRC4 table to avoid bit-reversal of each byte 
In commit 9bd2c9ffe7 we fixed the CRC4
computation by bit-reversing every byte before using it in the CRC
table.  This is of course a waste of CPU cycles.  Let's just compute
the CRC4 table slightly different (thanks to Dietter):

The following commands using pycrc from pycrc.org were used:
./pycrc.py --width=4 --poly=0x3 --reflect-in=false --reflect-out=false --xor-out=0 --xor-in=0 --algorithm table-driven  --generate c -o crc4itu.c
./pycrc.py --width=4 --poly=0x3 --reflect-in=false --reflect-out=false --xor-out=0 --xor-in=0 --algorithm table-driven  --generate h -o crc4itu.h

Harald Welte 9bd2c9ffe7 HACK to make CRC4 computation work 
* reverse bit-order of every input byte when computing CRC4
* reverse bit-order of CRC4 value we receive in TS0 bits

I don't really understand why, but this makes the CRC check pass.
We probably need another table if we want to avoid this.
