Preliminary

Stratix II and HardCopy II Companion Memory Blocks

Table 8–15 shows the differential termination support.

Stratix II and

HardCopy II

Companion

Memory Blocks

HardCopy II device RAM bit offerings range from 663 kbits to 8.8 Mbits.

HardCopy II memory blocks are functionally equivalent to the Stratix II

memory blocks. HardCopy II memory blocks can implement various

Stratix II device memory configurations, including simple and true dual

port modes, FIFO, parity bits, ROM modes, and all other features, as

listed in the HardCopy II Description, Architecture, and Features chapter of

the HardCopy Series Handbook. One difference between HardCopy II and

Stratix II devices is that HardCopy II devices do not support M512 blocks.

Additionally, you cannot pre-load HardCopy II M4K blocks with a

Memory Initialization File (.mif) when used as RAM.

Table 8–16 shows all the memory block offerings when compiling for a

Stratix II FPGA in conjunction with a HardCopy II companion device.

Use Table 8–16 as a guide when optimizing memory requirements for

selected Stratix II and HardCopy II pairs.

Notes to Table 8–15:

(1)

HC230, HC220, and HC210 device left clock pins

CLK0 and CLK2 support differential on-chip termination.

(2)

All other clock pins, including

FPLL[7..10]CLK, do not support differential on-chip termination.

(3)

HardCopy II HC240 device clock pins

CLK0, CLK2, CLK8, and CLK10 support differential on-chip termination,

similar to Stratix II devices.
