Mercury Programmable Logic Device Family Data Sheet

Mercury device HSDI performance is finalized for certain speed

grades. Also, the industrial-grade CDR specification is the same

as the -6 speed grade for commercial-grade CDR specification.

See Table 8.

Notes to Table 8:

(1)

The -6 speed grade specifications apply for both commercial and industrial devices.

(2)

EP1M350 devices can support any 8 channels at 1.25 Gbps. The other 10 channels must run at 1.0 Gbps or less.

Logic &

Interconnect

Mercury device logic is implemented in LEs. LE resources are used

differently according to specific operating modes and the type of logic

function being implemented. LEs are grouped into LABs in a row-based

architecture. The multi-level FastTrack Interconnect structure provides

the routing connection between LEs, ESBs, and IOEs.

Logic Array Block

Each LAB consists of 10 LEs, LE carry chains, multiplier circuitry, LAB

control signals, local interconnect, and FastLUT connection lines. The

local interconnect transfers signals between LEs within the same or

adjacent LABs. FastLUT connections transfer the output of one LE to the

adjacent LE for ultra-fast sequential LE connections within the same LAB.

The Quartus II Compiler places associated logic within a LAB or adjacent

LABs, allowing the use of fast local and FastLUT connections for high

performance. Figure 5 shows the Mercury LAB structure.
