jatin jatin posted a topic in SystemC LanguageHi all, i'm implementing a timer/counter(8-bit) that should not increment on every clock and i'm not supposed to provide any input clock port . But i need clock period in my design so my question is " How would i provide clock period(through constructor)?" here is the link to my working code on EDAplayground : http://www.edaplayground.com/x/4_dY if there is any problem in my code please feel free to tell me. regards, jatin
Implement a timer at LT level
thundium posted a topic in SystemC TLM (Transaction-level Modeling)Hi All: Get to implement a timer module in SytemC-TLM. And it is at LT level. The Time used for interrupt generation is from sc_time_stamp. My current implementation is using TLM payload event queue, which means the timer caculates the expected wait time for the request and do "notify(x ns)" for the payload event queue. Which the drawback is: 1.When I add the cancel function for a ongoing time request, I can't delete the "time request" from the event queue. I do a workaround like saving some tags when the timeout happened to achieve the "cancel" 2.When I add a stop function for the timer, I also need a tag and did lots of workaround in order to fullfil the stop/re-start function. So, is there any foward way to do this? If i do my own queues instead of using Payload event queue(But I guess I still need to use notify(x ns) in some way), may I somehow delete a ongoing requests? Thanks BR
