Negative leakage power of an SRAM in HSPICE

[electronics20]

Hi,
I have simulated a 6T conventional SRAM by hspice. Its value of leakage power is achieved negative one about -75nWatt. What's the problem?
By the way, another issue adumbrating my results is peculiar current spike of pulse sources associated with BL and BLB as shown in attached Fig.
Many thanks in advance

Hi,

Please share how you are doing the analysis; if it's through spice, it's suggested to check the stimuli, such a behavior is usually observed due to bad stimuli.

Thanks.

Yes, it is HSPICE. What's the stimuli specifically?
Thanks
