    Buses not showing in Xilinx ISE RTL schematic

    Thnx But technology schematic show the look up tables I want to see the design with all of its buses in the register level How can i do that ? And why are certain buses trimmed and other appear ?

    Buses not showing in Xilinx ISE RTL schematic

    in Xilinx ise, when i view the RTL schematic of a module, some buses are connected between the i/o ports and the module and other buses are not connected, what is the reason for this ? This is an example for what i mean : Select signal and output are not connected, while the rest is.

    Building memory design using design compiler

    I want to build a simple memory module in design compiler How can I write the VHDL or Verilog code in order for the compiler to build the module using SRAM cells ? Is there a tutorial or an open source code for a memory module than can be compiled to produce an actual design with SRAM cells ...

    4 Resistor MOSFET P-MOS

    Vgs = Vg - Vs so it's the voltage rise from the source to gate you can say it's like an arrow pointing from S to G so in the equation you wrote it's Vsg not Vgs , as u pass by G then S on your way from GND to VDD (voltage rise is from gate to source).

    How to sense mV range signal with ADC with Vref+=3.3V?

    If your ADC was 10 bit resolution then u can sense a change of 3.3/(2^10) \[\approx\] 3.2 mv so u can represent your signal in 150/3.2 \[\approx\] 47 steps, u can use ADC directly if this step is fine by you, or u can amplify the signal to span the full possible 1024 steps, u can do this by a...

    4 Resistor MOSFET P-MOS

    I solved this starting from the loop equation from GND to VDD through VGS, u get VGS = 2ID - 4 , substitute in the ID - VGS relation, get ID and VGS , that should be 0.608 and -2.784 , get VDS from the remaining loop (-6.9) the other value yields VDS < VGS-VTP

    how to serve INT0, while INT1 is servicing.

    You will have to re-set the global interrupt flag : place sei(); before jumping to a vector table and check this too(the nested interrupts section) : https://www.nongnu.org/avr-libc/user-manual/group__avr__interrupts.html
