Chapter 4:

Signal Integrity Recommendations and Simulations

Data Signal Simulations

All of the data signal simulation use the following test conditions for typical, slow/weak,
and fast/strong cases:

•

Topology for data signals: 50-ohm transmission lines

•

Transmit:

♦

At the memory: 100-ohm parallel split termination pulled-up to V

= 1.8 V

(equivalent to a 50-ohm termination pulled up to V

ref

= 0.9V)

♦

At the FPGA: HSTL_18_C2 drivers

•

Receive:

♦

At the FPGA: HSTL_18_C1_DCI receivers (internal termination, VRP, and VRN
pins connected to reference resistors)

Figure 4-1

shows signal terminations for transmitted and received data.
