    DFT logic auto insertion

    In a design we put logic for DFT and we call it design for test. For example we place AND gates in design to detect stuck at 1 fault. What are the tools which can auto insert this kind of DFT logic in rtls or in netlist and in which phase of a design flow these kind of DFT logic can be auto...

    Internal logic of IO pads

    Do IO Pads have any digital logiv inside them? What is the purpose of that digital logic inside them?

    BIST rtl generation automatically

    What are the available tools to generate BIST rtls for a logic or block for which we require BIST to be present?

    Availability of IO Pads

    The IO Pads are present in rtls. To realize these IO Pads we require gates. Do foundries provide the .lib/library of IO Pads separately from standard cells and macros? Can this IO pad library be provided during synthesis of rtls? Are these IO Pads are available from any other place other...

    Boundary scan insertion

    Which tools are typically used for boundary scan insertion? What are all the stages during design flow at which boundary scan can be inserted?

    Simultaneous read and write in memory

    What phenomenon happens when a read and write operation is requested at the same clock cycle for a single port memory?

    Using binary number as replicator in the replication operator

    Does it mean that even an expression can work as replicator?

    shifting value in binary instead of decimal in rtl

    Can the shifting value in the shift operator which is shown below be binary? <<, >>. For example, in the below the shifting value 4'b0101 is in binary. Is it valid to write synrhesizble rtl code with the shifting value in binary as shown below? assign d = b << 4'b0101 to shift b left by 5...

    Using binary number as replicator in the replication operator

    Can m be binary numbers in the replication operator which is shown below? Here m is the replicator. {m{variable for replicating}} For example, in the below example a is replicated by 4'b0100. So m in below example is 4'b0100. Is it valid to write synrhesizble rtl code with the m in binary as...

    Simultaneous Read and Write in AHB

    What do you mean you echo of write data? What did you mean by "HRDATA is shown to echo HWDATA at write cycle end" Do you want to mean that write and read cannot happen simultaneously in AHB?

    Simultaneous Read and Write in AHB

    By simultaneous READ and WRITE it is being indicated that Master can issue a READ and a WRITE transaction in the same clock cycle. 1697778215 In AHB specification in the timing diagrams READ and WRITE waveforms are shown in the same diagram. From that it appears if it means simultaneous READ and...

    Maintaining proper shape of clock

    Do you want to mean that to use an external PLL and send the same clock to the Clk pin of the SOC and the clk pin of blk_A? 1697686938 What do you mean by this? 1697687221 Let the problem be stated more clearly: There is a SOC named SOC_S and a clock named Clock_S comes as an output of SOC_S...
