Dear Webench team,
The customer who created this online schematic wanted to test a refresh cycle down to about 7.8us, but has said that Webench only allows him to go down to 330us. See below:
“This buck 1V2 will be use for the POL of DDR4 4Gb (256Mb x16). The DDR4 are very demanding on load transient on the refresh cycle (50mA avg to peak 250mA). The refresh cycle period is 260ns.
I would like to do some simulation on the Webench with this type of refresh cycle vs load transient (period 260ns, 50mA T0+130ns, 250mA T130ns+130ns). Can this short period of cycle can be done on Webench? I did try but is limit to period of only 300us.”
Is this a limitation in the software? Are we able to get more granular on the time axis, or does Webench limit to 300us?
