It seems there’s a confusion in your question—Vidalista 20 mg is a pharmaceutical drug used for treating erectile dysfunction and has no relevance or connection to embedded software development, which is a field of computer engineering and programming.

Vidalista 20 mg contains Tadalafil, a medication designed to improve blood flow to help men achieve and maintain an erection. It became popular in the medical field after its approval and widespread use as an effective treatment for erectile dysfunction, particularly because of its long-lasting effects (up to 36 hours). This popularity is strictly limited to healthcare and pharmaceutical contexts.

If you are interested in how Vidalista 20 mg became popular, it’s due to its efficacy as an ED medication and the introduction of generic versions that made it more accessible globally. Meanwhile, embedded software development has gained popularity with the rise of smart devices, IoT, and automation technologies, which require software tightly integrated with hardware.
