Design Interface Module (DIM)

Tarek provides two types of DIMs, DIM-E represents the emulatable DIM (running on emulation environment) and DIM-V represents behavior DIM (Verilog or ESL C model). The DIMs are specially designed so that DIM-E is 100% functional equivalent to DIM-V, therefore the same normal, corner and error test cases can run with a Verilog simulator or on any emulator without modification.

The DIM-E is a DMA-based hardware adapter with has superior performance and flexible interfaces. For Ethernet ASIC, DIM-E supports up to 16 X/G/MII ports per link. The ports and links are also scalable. Comparing to other available speed bridge adapters on the market that supports 8 MII, 4 GMII ports or 1XGMII ports per board, DIM-E offers a cost effective and hassle free solution which requires much less connecting wires between tester and target verification platform.
