  • Need to place a pin on the symbol for an internal VerilogA signal

    I have an internal signal in my VerilogA code that is passed to another module, and it is not on this module's port list. But when netlisting, it complains that it wants a pin on the symbol for that signal. So my temporary solution is just to place it on the symbol and then as a no-connect on a schematic...

  • Verilog in and spice out procedure?

    Dear all, I want to convert a verilog netlist into a simulatable SPICE (or HSPICE) format. I have seen people talking about verilog-In and spice out. How does this process actually work? What are the tools I should use? Thank you so much!

  • Error : Verilog-2001 feature.

    Dear all, I am trying to synthesize a design using RTL compiler (Version v07.10-p004_1 (32-bit), built Jun 18 2007). The tool gives the following error information: always @* begin | Error : Verilog-2001 feature. [VLOGPT-3] [read_hdl] : Implicit event expression in file 'gcm.v' on line 199, column...

  • Improve Debug Productivity - SimVision Video Series on YouTube

    Most verification customers claim that they are spending over 50% of their verification effort in debug. If so, you should check out these latest SimVision debug videos since you will quickly see how SimVision can enable you to be much more productive in less than an hour after viewing the videos. Take...

  • Handling rc/encounter generated pins in virtuoso

    Hi, I have been working with a digital block made in SystemVerilog and instantiated into a larger analog design. The HDL was imported into the corresponding cell views in virtuoso and symbols were generated for all hierarchical cells. After running synthesis and P&R the resulting netlist and layout...

  • IEEE Award Honors Stan Krolikoski as EDA Standards Pioneer

    EDA standards are a crucial enabler of today's complex electronic design flows - and it takes a lot of hard work to create them. Few know this better than Stan Krolikoski, who got involved with VHDL standardization in the early 1980s and has taken a leadership role in standards development ever since...

  • Re: How to get the activity power in Simvision

    Run a simulation (RTL or netlist) and dump your VCD file. In RTL Compiler: read the design (RTL or netlist, the same way as above. If VCD file is generated from RTL, read the RTL. If VCD file is generated from netlist, read netlist). elaborate the design. Then I will show another technique: call the...

  • Webinar: Is SystemVerilog the Future of Mixed-Signal Modeling?

    Real number modeling (RNM) provides a fast way to run a chip-level simulation with analog values, but support for it in the current SystemVerilog Language Reference Manual (2009 LRM) is very limited. A recently archived webinar shows how the next SystemVerilog LRM (which may be dated 2012 or 2013) offers...
