As a backup plan I had in mind to tape-out some other CPU like a SwerV RISC-V core from Western Digital. Alternatively some of the budget could be used so I can look into multi-port RAMs and register files; maybe I can have a closer look at a PLL also. These could first be tested on 0.35um which costs a lot less (ca. $5000 vs. ca $20000). There is question about funding. It takes about 3 months after tape-out to get the chips and then the debugging of the chip can only begin which typically also takes a lot of time. So if we delay the tape-out the completion of the testing of the chip will miss the deadline for the current NLNet funding. I am currently supposed to do the testing of the chip but I won't start that if I don't know if I can get the funding for it. 0.18um TSMC MPW runs are done at least once a month. You can find the schedule online: https://europractice-ic.com/wp-content/uploads/2020/05/General-MPW-EUROPRACTICE-200505-v8.pdf So last two tape-out dates this year are 18/11 and 2/12 (I think 2/12 was not there in a previous version of the file). greets, Staf.
