NOTE: Speed Grade c6 used for analysis
NOTE: Memory device can operate at 85.00 MHz with a lower CL than 2.5
DDR read data capture: DDR Data to DQS strobe edges at capture registers.
Setup slack is 1949 ps associated with pin 'ddr_dq[1]' ( variation port 'dq(9)', 'input_cell_H[0]')
Hold slack is 1492 ps associated with pin 'ddr_dq[3]' ( variation port 'dq(11)', 'input_cell_L[0]')
Read data resynchronisation: Captured data to resync clock at resync registers ('resynched_data').
Setup slack is 4682 ps associated with pin 'ddr_dq[2]' ( variation port 'dq(10)', 'input_cell_H[0]')
Hold slack is 756 ps associated with pin 'ddr_dq[4]' ( variation port 'dq(12)', 'input_cell_H[0]')
Read Postamble Enable: Enable-release to DQS strobe postamble period at negative-edge capture registers.
Setup slack is 2000 ps associated with pin 'ddr_dq[0]' ( variation port 'dq(8)', 'input_cell_L[0]')
Hold slack is guaranteed by design to always be positive for Cyclone II
Read Postamble Control: Preset-release ('dq_enable_reset') to DQS strobe negative edges at postamble register ('dq_enable').
Setup slack is 4665 ps associated with pin 'ddr_dq[0]' ( variation port 'dq(8)', 'input_cell_L[0]')
Hold slack is 3185 ps associated with pin 'ddr_dq[4]' ( variation port 'dq(4)', 'input_cell_L[0]')
