Sergiu Arpadi 3be5137aec cn0540/cora: Remove multicycle constraint 
Design uses 80MHz spi_clk which does not require
special considerations

sergiu arpadi acbbd4636a sysid: Upgrade framework, header/ip are now at 2/1.1.a 
Unify tcl scripts; rename adi_pd_intel.tcl to adi_pd.tcl
add git branch to internal use area; update log prints;
update xilixn projects; fix cn0506 sysid script;

Adrian Costina 9093a8c428 library: Move ad_iobuf to the common library, as it's not Xilinx specific 
Updated all system_project and Makefiles

Sergiu Arpadi 72635d73e3 cn0540: Add axi_clkgen to Makefile 2020-10-14 00:05:57 +03:00
Sergiu Cuciurean da6d9da4f0 projects: cn0540: coraz7s: Add XADC support 
The coraz7s has an Arduino/chipKIT Shield connector with 6 Single-ended
and 8 Differential Analog inputs tied to Xilinx's XADC.
The CN0540 uses the A0-5 pins as single-ended ADC channels to monitor
the differential input, ADC driver, and buffer voltages.

Istvan Csomortani 11822e2824 cn0540/coraz7s: Set and input delay of one spi_clk cycle for the MISO line 
Note, the current SCLK to spi_clk ratio is four. That means, the input
delay in the MISO line is 25% of the SCLK period.

If the SCLK to spi_clk ratio is changing, this constraint must be
updated.

Istvan Csomortani dae1de0405 cn0540/bd: Generate a 80MHz spi_clk 
Generate a higher frequency of spi_clk using an axi_clkgen. (MMCM)

CAUTION: ad7768-1 is still violating the standard SPI timing,
reducing the timing window significantly for the last bit (or last high
bit).
