Constraints for the SDI Soft Transceiver
Cyclone Devices Only
These constraints apply to Cyclone devices only (not Cyclone II, Cyclone III, or other
device families).
Classic Timing Analyzer
Use the following constraints for the Classic timing analyzer:
set_global_assignment -name FMAX_REQUIREMENT "27 MHz" -section_id
input_refclk
set_instance_assignment -name CLOCK_SETTINGS input_refclk -to
rx_27_refclk
set_instance_assignment -name CLOCK_SETTINGS rxclk -to
"<your_megacore>|sdi_megacore_top:sdi_megacore_top_inst|sdi_clocks:u_s
di_clocks|clkdiv_2p5:cyc_rx_pll_gen.u_clkdiv|clkdiv"
set_global_assignment -name BASED_ON_CLOCK_SETTINGS input_refclk -
section_id rxclk
set_global_assignment -name MULTIPLY_BASE_CLOCK_PERIOD_BY 5 -section_id
rxclk
set_global_assignment -name DIVIDE_BASE_CLOCK_PERIOD_BY 25 -section_id

TimeQuest Timing Analyzer
Use the following constraints for the TimeQuest timing analyzer:
derive_pll_clocks -use_tan_name
create_clock -name rx_27_refclk -period 37.037 -waveform { 0.000 18.518
} [get_ports {rx_27_refclk}]
create_clock -name tx_27_refclk -period 37.037 -waveform { 0.000 18.518
