Cadence Design Systems: V1995: Cycle based simulator originally developed at DEC. The DEC developers spun off to form Quickturn Design Systems. Quickturn was later acquired by Cadence, who discontinued the product in 2005. Speedsim featured an innovative slotted bit-slice architecture that supported simulation of up to 32 tests in parallel ...
Cadence has a number of digital implementation and signoff tools, including Genus, Innovus, Tempus & Voltus, among others. In 2020, Cadence integrated its Innovus place and route engine and optimizer into Genus Synthesis. [47] Stratus is Cadence's high-level synthesis tool, and is used to create RTL implementations from C, C++, or SystemC code ...
Cadence Tensilica develops SIP blocks to be included on the chip (IC) designs of products of their licensees, such as system on a chip for embedded systems. Tensilica processors are delivered as synthesizable RTL to aid integration with other chips.
When the system is run, the RTL-based probe connected to each of the instrumented signals collects the signal's value at each clock cycle. The data is stored in a trace buffer in FPGA block RAM. An analyzer connected to the prototype downloads the information giving the user offline visibility into the system for efficient debug. [3]
Physical design is based on a netlist which is the end result of the synthesis process. Synthesis converts the RTL design usually coded in VHDL or Verilog HDL to gate-level descriptions which the next set of tools can read/understand. This netlist contains information on the cells used, their interconnections, area used, and other details.
After listing out all the features in the specification, the verification engineer will write coverage for those features to identify bugs, and send back the RTL design to the designer. Bugs, or defects, can include issues like missing features (comparing the layout to the specification), errors in design (typo and functional errors), etc.
The flagship implementation, the OR1200, is a register-transfer level (RTL) model in Verilog HDL, from which a SystemC-based cycle-accurate model can be built in ORPSoC. A high speed model of the OpenRISC 1200 is also available through the Open Virtual Platforms (OVP) initiative (see OVPsim ), set up by Imperas.
acquired by Cadence Design Systems in Q2 of 2010 ECAD, Inc. merged with SDA Systems in 1987 to create Cadence Forte Design Systems: acquired by Cadence Design Systems [15] in 2014 Cynthesizer; Gateway Design Automation: acquired by Cadence Design Systems in 1989 Verilog HDL; Verilog-XL; IKOS Systems: acquired by Mentor Graphics in 2002 [16]
