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]
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.
This ambiguity is intentional. Wishbone is made to let designers combine several designs written in Verilog, VHDL or some other logic-description language for electronic design automation (EDA). Wishbone provides a standard way for designers to combine these hardware logic designs (called "cores"). Wishbone is defined to have 8, 16, 32, and 64 ...
Using high-level synthesis, also known as ESL synthesis, the allocation of work to clock cycles and across structural components, such as floating-point ALUs, is done by the compiler using an optimisation procedure, whereas with RTL logic synthesis (even from behavioural Verilog or VHDL, where a thread of execution can make multiple reads and ...
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 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 ...
The Vivado High-Level Synthesis compiler enables C, C++ and SystemC programs to be directly targeted into Xilinx devices without the need to manually create RTL. [15] [16] [17] Vivado HLS is widely reviewed to increase developer productivity, and is confirmed to support C++ classes, templates, functions and operator overloading.
ModelSim is a multi-language environment by Siemens [1] (previously developed by Mentor Graphics, [2]) for simulation of hardware description languages such as VHDL, Verilog and SystemC, and includes a built-in C debugger. [3] [2] ModelSim can be used independently, or in conjunction with Intel Quartus Prime, PSIM, [4] Xilinx ISE or Xilinx ...
