Synopsys has partnered with Ansys to integrate RedHawk family of silicon-proven analysis capabilities with 3DIC Compiler. ![]() Synopsys' 3DIC Compiler is built on an IC design data model – enabling scalability in capacity and performance with more modern 3DIC structures. These come with thousands of inter-die interconnects that are beyond the scope of traditional PCB-based packaging tools. Packaging, 3D architectures and low latency memory are being used to bypass the slowdown in Moore's Law and re driving such developments as chiplets and stacked-die. "Synopsys' 3DIC Complier with its unified platform is an industry disruptor in how advanced multi-die packages are designed, as it has redefined the conventional tool boundaries across the full design workflow for 2.5D/3D multi-die solutions," said Jaehong Park, executive vice president of Design Platform Development at Samsung Electronics, in a statement issued by Synopsys. One of the inhibitions on the uptake of 3D design to date has been the lack of EDA software.ģDIC Compiler provides architectural exploration, design, implementation, and signoff with signal, power, and thermal integrity optimizations, all in one solution. If Design Compiler reports timing violations in the timing report, increase the clock period until they go away.The software is based on Synopsys Fusion design platform and provides 3D viewing capabilities as well as integration with Ansys' software for system-level signal, power, and thermal analysis. If you leave too much slack, the compiler won't try hard at all-but it will be much faster. If you are too aggressive, the compiler will try very hard to meet your timing requirements (sometime with ridiculous results). Note that you can also increase or decrease the target clock period. Set_output_delay -clock clk -max 2.0 all_outputs() Set_input_delay -clock clk -max 2.0 real_inputs (The same goes for reset.) You must change the declaration in the following bold places to match your clock and reset port names: In particular, this should not be your test bench, since that will almost definitely contain external memory arrays, non-synthisizable Verilog (such as initialization or your clock module), and other things that would make the poor synthesis tool cry, if not croak.įinally, your clock name declaration in the top module must match the clock declared in the synthesis file (without this, the synthesis tool doesn't know which signal is a clock!). Note that your Top module should be the top logic module that you would like to synthesize. Similarly, your Top module can be set with: The Verilog source files are read with the command:Ĭlearly, changing the filename will change which file gets loaded into the compiler. You will have to read the documentations on your own if you really want to be good at this. Should you be motivated to modify the synthesis script, here is a quick run through. We do not suggest modifying the dc scripts beyond changing your top module and source files. The prized netlist should also be written to the current directory. Finally, it should begin mapping your Verilog description to the standard cell library and generate reports for area, power, and timing (output in area.rpt, power.rpt, and timing.rpt, respectively). If all goes well, the compiler should churn for a little time (or lots, depending on the complexity of your circuit). Error messages, on the other hand, are definitely bad news. You should investigate them, although many such warning messages do not indicate a show-stopper problem with your Verilog. Depending on what you did, you should also expect to see a number of common warnings. After this, it will read your Verilog file and load the technology library (in this case, an 180nm standard cell library). You should see a startup banner for Design Compiler and it should briefly print “Initializing…”. In your working directory with both your Verilog code (e.g., lab0.v) and the synthesis script (e.g., lab0.dc), run the following command on any of ECE's Linux machines: (You can find and replace these specific names in lab0.dc when you want to reuse the script in a future lab.) The FSM module must have a clock input port named clock and a reset input port named reset. These scripts are hard-coded to list which Verilog file(s) to compile, your top module for synthesis, and the name of your clock signal.įor lab0, to use /afs/ece/class/ece447/handout/lab0/lab0.dc, the module to be synthesized must be called FSM in a file called lab0.v.
