Struct xc2bit::XC2GlobalNets

pub struct XC2GlobalNets {
    pub gck_enable: [bool; 3],
    pub gsr_enable: bool,
    pub gsr_invert: bool,
    pub gts_enable: [bool; 4],
    pub gts_invert: [bool; 4],
    pub global_pu: bool,
}

Represents the configuration of the global nets. Coolrunner-II parts have various global control signals that have dedicated low-skew paths.

Fields

gck_enable: [bool; 3]

Controls whether the three global clock nets are enabled or not

gsr_enable: bool

Controls whether the global set/reset net is enabled or not

gsr_invert: bool

Controls the polarity of the global set/reset signal

false = active low, true = active high

gts_enable: [bool; 4]

Controls whether the four global tristate nets are enabled or not

gts_invert: [bool; 4]

Controls the polarity of the global tristate signal

false = used as T, true = used as !T

global_pu: bool

Controls the mode of the global termination

false = keeper, true = pull-up
