Florent Kermarrec 30a18808ad boards/targets: keep attributes are no longer needed since automatically added when applying constraints to signals. 2019-12-06 15:58:06 +01:00
Florent Kermarrec 23c33cfa99 build: automatically add keep attribute to signals with timing constraints.
Avoid having to specify it manually or eventually forget to do it and have a constraints that is not applied correctly.

Florent Kermarrec 4c9af635d2 build/altera/quartus: allow adding period constraints on nets and add optional additional sdc/qsf commands
Additional sdc/qsf commands can be added from the design like:
platform.sdc_additional_commands.append("create_clock ...")
platform.sdc_additional_commands.append("set_false_path ...")

spi_flash: correct documentation on SPI mode
2019-11-25 21:01:17 +01:00
Sean Cross 581c23725e spi_flash: correct documentation on SPI mode
The SPI mode is actually mode3, since the output value is updated on the
falling edge of CLK and the input value is updated on the rising edge.

This also clarifies some of the documentation based on experience with
the core.

Pawel Czarnecki fd14b76594 soc/cores/clock: add lock reg and assign reset
It was necessary to add drp_locked CSR for reading LOCK signal from
MMCM. Additionally, input signal RESET from MMCM was not driven by
any signal to do a proper reset of MMCM module thus it was impossible
to perform entirely correct dynamic clock reconfiguration.

soc_sdram, bios/sdram: support sdram init for csr_data_width <= 32
2019-11-18 18:24:35 +01:00
Gabriel Somlo 3ef13fd27a soc_sdram, bios/sdram: support sdram init for csr_data_width <= 32
Enable SDRAM to be initialized when csr_data_width > 8 bits.
Currently, csr_data_width up to 32 bits is supported.

Read leveling tested with csr_data_width [8, 16, 32] on the
ecp5-versa5g and trellisboard (using yosys/trellis/nextpnr),
and on the nexys4ddr (using Vivado).
