    Design Simulation Capability
    A powerful feature of PAC-Designer is its simulation
    capability enabling quick and accurate verification of
    circuit operation and performance. Once a circuit is
    configured via the interactive design process, gain and
    phase response between any input and output can then
    be determined. This function is part of the simulator
    capability which derives a transfer equation between the
    two points and then sweeps it over the user-specified
    frequency range. Figure 13 shows a typical screen plot of
    the gain/phase simulator. In it are the input to output
    response curves of a 2nd order biquad filter similar to the
    implementation illustrated in Figure 7b. In this example,
    the lowpass and bandpass characteristics of the filter are
    seen.
    The simulator is capable of displaying up to four separate
    input to output responses. This allows multiple signal
    paths to be viewed as well as intermediate results of
    component changes so performance comparisons can
    be made. There is also a user positioned crosshair cursor
    that intersects the curves on the plot, and reads out the
    gain and frequency in the lower right hand corner of the
    plot window when activated.
    In-System Programming
    The ispPAC10 is an in-system programmable device.
    This is accomplished by integrating all high voltage
    programming circuitry on-chip. Programming is performed
    through a 5-wire, IEEE 1149.1 (JTAG) compliant serial
    port interface at normal logic levels. Once a device is
    programmed, all configuration information is stored in on-
    chip, non-volatile E
    2
    CMOS memory cells. The specifics
    of the IEEE 1149.1 serial interface are described in the
    interface section of this data sheet.
    User Electronic Signature
    A user electronic signature (UES) feature is included in
    the E
    2
     memory of the ispPAC10. It contains 8 bits that can
    be configured by the user to store unique data such as ID
    codes, revision numbers or inventory control data.
