    Verilog code for Wallace tree encoder

    Yes, but how can I write it in Verilog? :\ Sorry, I'm new on that.

    Verilog code for Wallace tree encoder

    Hi, I need to design a Wallace Tree Encoder of 4 to 2 bits in Verilog - System, but I don't know exactly how to start the verilog code because I don't find the algorithm to be implemented. I just have the input/output definitions at this moment, but not the combinational blocks. Can you give...

    Well Proximity Effects (WPE): Is there any difference between PMOS and NMOS devices?

    Hi, I made a research about WPE and I have seen that below some distance there is not any difference between PMOS and NMOS devices, i.e. in both cases the voltage threshold increases. But I am not sure if this conclusion is correct or if there are another properties that can be different due...

    Gold vs Aluminum for bonding balls

    Why is it better to use a gold bonding ball instead of aluminum to reduce power supply noise? Is it maybe about the effective inductance?

    Verilog-A error in PMOS devices while using spectre with virtuoso

    Hi, I've installed the Cadence software and a new hitkit in local in Xubuntu 20.04, but when I try to run a simulation with Pmos the following errors appear in the log file: Error found by spectre during AHDL read in. ERROR (VACOMP-1008): Cannot compile ahdlcmi module library. Check the...
