Good day, I have a question regarding how to determine the appropriate delay value for the wait( ) function call. In the target b_transport callback, we can add delay to the simulation time by passing delay amount to the wait( ) function. In simulation that uses quantum and temporal decoupling that targets super fast instruction accurate simulation, the timing does not have to be very detail (loosely timed). With or without delay in the target callback function will not cause any functional inaccuracy and still we could produce the platform that can support firmware/software development. Still if we want to put a delay to the wait( ), how can we determine the appropriate delay value for the function parameter? Thank you. Regards, Arya.
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
Hi Can anybody please tell me how to write a transactor for an existing System C model? I can write a systemC model as well as a LT TLM model. But i don't know how to interconnect both of them using ports. Any valuable help would be appreciated. Thanks
