    Concept of Routing Congestion

    Congestion in general referred to routing. Placement congestion is due to overlap of standard cells, it is called overlapping rather than called as congestion. Routing congestion is difference between supplied and available tracks. A track is nothing but a routing resource. Tracks fill...

    what is the inputs and outputs of the placement and CTS ?

    floorplan is the input for placemnet . CTS specification file is input for CTS and .cts.rpt is the output report after CTS.

    Need help with synthesis and layout in 130nm design

    Re: 130nm design you can use source link to get the help.

    What is the setup and hold time?

    setup check hold check thanku satya for your material.

    What is capacitive loading? How does it affect slew rate?

    Re: STA Useful is nothing but skewing the clock inorder to fix the timing violations. you can borrow the positive slack from the previous path and can fix the violation for the present one.

    How do you avoid antenna DRC violation?

    Re: Antenna Violation by adding the antenna diodes or by doing the metal hopping you can reduce the antenna violations.

    Several questions about STA

    how to solve reg2reg hold you cannot reduce the clock skew to zero because on chip variations. virtual clock is used to constrain the input to output (timing path) in your design.

    Need of Endcaps in design?

    please discuss about endcap cells used at the stage of place and route.

    Which institutions or universities are offering an MS or M. Tech in VLSI ?

    Re: MS or M.Tech in VLSI Hi Kumar_eee, even i want to know about institutions or universities which are offering MS or M. Tech in VLSI abroad.I am in INDIA now. thnxs

    WHy we use NAND gate only in CMOS than NOR gate

    why we use nand gate NAND have equal rise and fall times..that why its faster

    How to fix the design rule violations in clock tree synthesis using Encounter?

    cts Hi Priya_j, DRV violation include three things 1.Max Cap 2.Max Tran 3.Max Fanout First, one should fix Max cap, that you can do by including Max Cap statement in cts specification file.You assign cap value for a buffer by using this statement.Cap value you decide by looking int SDC...

    what is the flase path and multiple path in physical design

    if you have more logic between registers ...to over come that dalay we should use more than one clock cycle...that path is called multi cycle path
