I did use also Mock components, in first version of FPGAmstrad, FPGA platforms was too small, so I could have FPGAmstrad only with cool sound and low graphics, or else FPGAmstrad with cool graphics and no sound. Both using 100% of this old FPGA platform. A Mock component is a fake component, an empty one, just telling back "I'm OK, please thrust me I do exist" to others components trying to communicate with me (it's a entity with same in out ports as original but using constant output values)
* * for programming a FPGA, the compiled binary is around 180KB, so do not expect about creating a RAM in FPGA itself. FPGA does contains also internal RAM (seduce ones, that can using two clock entries [[RAM_dump]] ==== Third schematic video ====https: one clock for data in an another for data out <3), but it is about 32KB//www. So an external 600KB RAM is best friend of FPGAyoutube.com/watch?v=w_wifI-bRJc
