for the inout runstop_irq_en signal i have declared
assign runstop_irq_en = runstop_irq_en_reg;
in interface and then used runstop_irq_en_reg to assign values to inout port in program block.
From the top module everything is working fine but the runstop_irq_en signal is showing up x in the waveform but runstop_irq_en_reg signal is working accordingly.
Can anyone help me out with this to debug and fix the issue, so that runstop_irq_en shows up the content.
