Register-transfer-level abstraction is used in hardware description languages (HDLs) like Verilog and VHDL to create high-level representations of a circuit, from which lower-level representations and ultimately actual wiring can be derived. Design at the RTL level is typical practice in modern digital design. [1]
Catapult has a graphic user interface with a visual view of the hardware circuit it is scheduling, as well as the clock reference between the C code and the Verilog RTL code. Catapult C has 3 types of simulation using the original C/C++ testbench: Cycle-based, RTL-based, and Gate-Level based.
The XGMII is organized into four lanes with each lane conveying a data octet or control character on each edge of the associated clock. The source XGXS converts bytes on an XGMII lane into a self-clocked, serial, 8b/10b encoded data stream. Each of the four XGMII lanes is transmitted across one of the four XAUI lanes.
Virtex is the flagship family of FPGA products currently developed by AMD, originally Xilinx before being acquired by the former. [1] Other current product lines include Kintex (mid-range) and Artix (low-cost), each including configurations and models optimized for different applications. [2]
Initially the RTL description in VHDL or Verilog is simulated by creating test benches to simulate the system and observe results. Then, after the synthesis engine has mapped the design to a netlist, the netlist is translated to a gate-level description where simulation is repeated to confirm the synthesis proceeded without errors.
Logic design is a step in the standard design cycle in which the functional design of an electronic circuit is converted into the representation which captures logic operations, arithmetic operations, control flow, etc. A common output of this step is RTL description. Logic design is commonly followed by the circuit design step.
SystemVerilog for register-transfer level (RTL) design is an extension of Verilog-2005; all features of that language are available in SystemVerilog. Therefore, Verilog is a subset of SystemVerilog. SystemVerilog for verification uses extensive object-oriented programming techniques and is more closely related to Java than Verilog. These ...
The core achieves 1.34 CoreMarks per MHz at 50 MHz on Xilinx FPGA technology. [2] Under the worst case, the clock frequency for the OR1200 is 250 MHz at a 0.18 μm 6LM fabrication process. Using the Dhrystone benchmark, a 250 MHz OR1200 processor performs 250 Dhrystone millions of instructions per second (DMIPS) in the worst case. Estimated ...
