Chapter 7: ML561 Hardware-Simulation Correlation

DDR2 DQ is a bidirectional signal. To perform hardware measurements for a Write

operation that is not interrupted by a Read response or a Refresh operation, the testbench

on FPGA1 is controlled by DIP switches (SW2) as indicated in Table 7-3.

Table 7-3: DIP[1:2] Settings

Setting Description

2’b00 or 2’b11 Normal alternating Write/Read sequence

2’b01 Write only, Refresh disabled

2’b10 Write once, then Read only, Refresh disabled

1 2 ... 55 56 57 58 59 60 61 62 63 64 65 ... 139 140
