Take a look at the softdevice release notes when you download the softdevice. This documentation can also be found here:nRF5_SDK_15.0.0_a53641a\components\softdevice\s140\doc\ In addition, there is some more information available in the softdevice specifications in Section 14.1 "Memory Resource map & Usage".
Take a look at the nrf connect for desktop programmer app. There, you can read out the ROM usage & where the softdevice, application and/or bootloader are located in flash. This documentation might be helpful for Keil. Take a look at the bottom of the map file (e.g. nrf52832_xxaa.map in the _build folder), where you can see the different ROM & RAM sizes. Here is an example below:
Total RO Size (Code + RO Data) 22320 ( 21.80kB)
Total RW Size (RW Data + ZI Data) 10648 ( 10.40kB)
Total ROM Size (Code + RO Data + RW Data) 22400 ( 21.88kB)
==============================================================================
I am not sure whether you have the graphical RAM & ROM usage in Keil like you do in SES, but you can also see how much ROM & RAM you've allocated in the Target tab under Options for Target in Keil.
Total RO Size (Code + RO Data) 46076 ( 45.00kB) Total RW Size (RW Data + ZI Data) 13040 ( 12.73kB) Total ROM Size (Code + RO Data + RW Data) 46176 ( 45.09kB)
