Missing Libraries: If a simulation fails with "Component not found," ensure you have mapped your work library correctly using the vlib work and vmap work work commands.
I understand you're looking for a QuestaSim 10.7c download, but I need to provide an important heads-up first:
QuestaSim is a commercial HDL simulator from Siemens EDA (formerly Mentor Graphics). It is not free for most users, and the 10.7c release is now quite old (legacy version). Direct downloads are not publicly available from unofficial sources without violating copyright laws.
That said, here’s a helpful, legitimate post you could use to guide others:
Quick guide — download and install QuestaSim 10.7c (assumes Windows or Linux)
Warning: Questa/ModelSim is commercial EDA software. You must have a valid license and entitlement from Siemens EDA (formerly Mentor Graphics) or an authorized distributor before downloading or running it.
2) Get access to the Siemens EDA Support Center
- Log in to the Siemens EDA Support/Portal with the account tied to your entitlement (customer/support account). Downloads for Questa/ModelSim are distributed from Siemens’ support/download site; public mirrors are unreliable and may be unsafe.
